ASTM D6296-22 多维气相色谱法测定火花点火发动机燃料中总烯烃的标准试验方法

1.1 This test method provides for the quantitative determination of total olefins in the C4 to C10 range in spark-ignition engine fuels or related hydrocarbon streams, such as naphthas and cracked naphthas. Olefin concentrations in the range from 0.2 % by liquid-volume or mass to 5.0 % by liquid-volume or mass, or both, can be determined directly on the as-received sample whereas olefins in samples containing higher concentrations are determined after appropriate sample dilution prior to analysis. 1.2 This test method is applicable to samples containing alcohols and ethers; however, samples containing greater than 15 % alcohol must be diluted. Samples containing greater than 5.0 % ether must also be diluted to the 5.0 % or less level, prior to analysis. When ethyl-tert-butylether is present, only olefins in the C4 to C9 range can be determined. 1.3 This test method can not be used to determine individual olefin components. 1.4 This test method can not be used to determine olefins having higher carbon numbers than C10. NOTE 1—Precision was determined only on samples containing MTBE and ethanol. 1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Method for Total Olefins in Spark-ignition Engine Fuels by Multidimensional Gas Chromatography

ASTM D6866-22 用放射性碳分析法测定固体、液体和气体样品中生物基含量的标准试验方法

1.1 This standard is a test method that teaches how to experimentally measure biobased carbon content of solids, liquids, and gaseous samples using radiocarbon analysis. These test methods do not address environmental impact, product performance and functionality, determination of geographical origin, or assignment of required amounts of biobased carbon necessary for compliance with federal laws. 1.2 These test methods are applicable to any product containing carbon-based components that can be combusted in the presence of oxygen to produce carbon dioxide (CO2) gas. The overall analytical method is also applicable to gaseous samples, including flue gases from electrical utility boilers and waste incinerators. 1.3 These test methods make no attempt to teach the basic principles of the instrumentation used although minimum requirements for instrument selection are referenced in the References section. However, the preparation of samples for the above test methods is described. No details of instrument operation are included here. These are best obtained from the manufacturer of the specific instrument in use. 1.4 Limitation—This standard is applicable to laboratories working without exposure to artificial carbon-14 (14 C). Artificial 14 C is routinely used in biomedical studies by both liquid scintillation counter (LSC) and accelerator mass spectrometry (AMS) laboratories and can exist within the laboratory at levels 1,000 times or more than 100 % biobased materials and 100,000 times more than 1% biobased materials. Once in the laboratory, artificial 14 C can become undetectably ubiquitous on door knobs, pens, desk tops, and other surfaces but which may randomly contaminate an unknown sample producing inaccurately high biobased results. Despite vigorous attempts to clean up contaminating artificial 14 C from a laboratory, isolation has proven to be the only successful method of avoidance. Completely separate chemical laboratories and extreme measures for detection validation are required from laboratories exposed to artificial 14 C. Accepted requirements are: (1) disclosure to clients that the laboratory(s) working with their products and materials also works with artificial 14 C (2) chemical laboratories in separate buildings for the handling of artificial 14 C and biobased samples (3) separate personnel who do not enter the buildings of the other (4) no sharing of common areas such as lunch rooms and offices (5) no sharing of supplies or chemicals between the two (6) quasi-simultaneous quality assurance measurements within the detector validating the absence of contamination within the detector itself.

Standard Test Method for pH of Atmospheric Wet Deposition Samples by Electrometric Determination

CAN/CGSB-3.0 No. 14.3-2022 石油及相关产品的测试方法 用气相色谱法鉴定车用汽油中的成分的标准测试方法

This test method is a standard procedure for the determination of paraffins, olefins, naphthenes, aromatics and unknowns (P.O.N.A.U.) in automotive gasolines using gas chromatography and flame ionization detection (GC/FID). Individual hydrocarbon components greater than or equal to 0.01 % by mass are determined. Group types greater than or equal to 0.01 % by mass are determined by summing individual components. Oxygenated components greater than or equal to 0.01 % by mass, including alcohols and ethers, may be determined by this test method. See Annex A, Table A.2 for example of retention times and response factors for oxygenates at concentrations typically found in automotive gasoline. This method applies to automotive gasoline, ethanol-blended gasoline and denatured ethanol. See Section 10 for concentration ranges for individual compounds and hydrocarbon group types for which precision applies. Liquefied petroleum gas (LPG), naphtha, reformate, alkylate, blendstocks, and typical petroleum or petrochemical product may also be analyzed, however precision data was obtained only with automotive gasoline and denatured ethanol. The final boiling point of samples as defined by ASTM D86 should not exceed 225 °C, however individual hydrocarbons eluting to nC15 can be determined. Components such as water which do not elute from the gas chromatograph or which have little or no response in a FID are not determined. The water content can be determined by using ASTM D6304, Procedure A. The separation of individual hydrocarbons and oxygenated compounds by the procedure described in this test method is not absolute and will result in some peaks that represent coeluting components (see Annex A, Table A.2). Due to the possibility of coeluting peaks, the user is cautioned in the interpretation of the data. Toluene and 2,3,3-trimethylpentane may coelute. If isooctane (2,2,4-trimethylpentane) and 2,3,4-trimethylpentane are present in the gasoline sample, it is probable that the sample contains 2,3,3-trimethylpentane. The concentration of 2,3,3-trimethylpentane is almost certain to be less than the concentration of 2,3,4-trimethylpentane. When determining the concentration of toluene and 2,3,3-trimethylpentane, it is essential that the gas chromatographic integrator has individual peak processing capabilities including peak expansion and perpendicular drop. To detect 2,3,3-trimethylpentane and toluene, it is essential for these components to be within a 5:1 ratio of each other with either component having the greater concentration. If these components are present in a greater than 5:1 ratio, the toluene and 2,3,3-trimethylpentane may appear as a coeluted peak, thus causing the component in the smallest concentration to be integrated with the more concentrated component. Typically forty components with concentrations greater than 1 % by mass constitute an average of approximately 80 % by mass of automotive gasoline. From these forty components, this method identifies coeluting peaks for toluene, 2-methylhexane, methylcyclopentane and n-hexane (see Annex A, Table A.1). The forty components are identified in Table 5 by an asterisk beside its identification number. The number of coeluting peaks depends on the total number of individual components and the number of olefinic components present. The possibility of coeluting components increases with the increase of components detected after n-octane. Supplementary analytical techniques such as ASTM D1319 for olefins, D5580 and D5769 for aromatic components, D4815 and D5599 for oxygenates may assist in interpretation of data obtained by this method. The testing and evaluation of a product against this method may require the use of materials and/or equipment that could be hazardous. This document does not purport to address all the safety aspects associated with its use. Anyone using this method has the responsibility to consult the appropriate authorities and to establish appropriate health and safety practices in conjunction with any applicable regulatory requirements prior to its use. Units of measurement – Quantities and dimensions in this standard are provided in metric units from the International System of Units (SI units). This standard expresses the industry standard nominal measurements in North America of “% by mass” and “% by volume”. The SI equivalent expression for these units are % (m/m) and % (V/V) respectively.

ASTM D6144-22 毛细管气相色谱法分析AMS（α-甲基苯乙烯）的标准试验方法

1.1 This test method covers the determination of the purity of AMS (α-methylstyrene) by gas chromatography. Calibration of the gas chromatography system is done by the external standard calibration technique. 1.2 This test method has been found applicable to the measurement of impurities such as cumene, 3-methyl-2cyclopentene-1-one, n-propylbenzene, tert-butylbenzene, secbutylbenzene, cis-2-phenyl-2-butene, acetophenone, 1-phenyl1-butene, 2-phenyl-2-propanol, trans-2-phenyl-2-butene, m-cymene, p-cymene, and phenol, which are common to the manufacturing process of AMS. The method has also been found applicable for the determination of para-tertiarybutylcatechol (TBC or PTBC) typically added as a stabilizer to AMS. The impurities in AMS can be analyzed over a range of 5 to 800 mg/kg by this method. (See Table 2.) Based on the results in ASTM Research Report RR:D16-1022, summarized in Table 2, the limit of quantitation for these impurities averages 4 mg/kg, while the limit of detection averages 1.2 mg ⁄kg. 1.3 In determining the conformance of the test results using this method to applicable specifications, results shall be rounded off in accordance with the rounding-off method of Practice E29. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 This standard does not purport to address all the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 8. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Method for Analysis of AMS (α-Methylstyrene) by Capillary Gas Chromatography

CAN/CGSB-3.0 Nº 14.3-2022 石油及相关产品的测试方法 用气相色谱法鉴定车用汽油成分的标准方法

La présente méthode d’essai est une méthode normalisée permettant d’identifier les paraffines, les oléfines, les naphtènes, les composés aromatiques et les produits inconnus (P.O.N.A.I.) contenus dans les essences automobiles, par chromatographie en phase gazeuse et par détection à ionisation de flamme (CG/DIF). Les constituants hydrocarbonés individuels dont la teneur est supérieure ou égale à 0,01 % en masse sont déterminés. Les types de groupes dont la teneur est supérieure ou égale à 0,01 % en masse sont déterminés par la somme de tous les constituants. Les constituants oxygénés ayant une teneur supérieure ou égale à 0,01 % en masse, tels que les alcools et les éthers, peuvent être déterminés par la présente méthode d’essai. Voir le tableau A.2 de l’annexe A pour des exemples de temps de rétention et de facteurs de réponse pour les composés oxygénés à des concentrations que l’on trouve habituellement dans l’essence automobile. La présente méthode s’applique aux essences automobiles, au carburant à l’éthanol et à l’éthanol dénaturé. La justesse relative aux constituants individuels et aux groupes d’hydrocarbures s’applique uniquement aux plages de concentration indiquées à la section 10. Les gaz de pétrole liquéfiés (GPL), le naphte, le reformat, l’alkylat, l’essence de base et les produits pétroliers et pétrochimiques peuvent également être analysés; toutefois, les données sur la justesse ont été recueillies seulement pour l’essence automobile et l’éthanol dénaturé. Le point d’ébullition final des échantillons, comme il est défini dans l’ASTM D86, ne devrait pas dépasser 225 °C; cependant, celui des hydrocarbures individuels qui éluent jusqu’à nC15 peut être déterminé. Les constituants, comme l’eau, qui n’éluent pas par chromatographie en phase gazeuse ou qui ont une réponse faible ou nulle dans un détecteur à ionisation de flamme ne sont pas déterminés. La teneur en eau peut être déterminée à l’aide de la méthode A de l’ASTM D6304. La séparation des hydrocarbures individuels et des constituants oxygénés à l’aide du mode opératoire de la présente méthode d’essai n’est pas absolue et se traduira par la présence de certains pics correspondant à des constituants coélués (voir le tableau A.2 de l’annexe A). L’utilisateur doit faire preuve de prudence lorsqu’il interprète les données, car il pourrait y avoir des pics de coélution. Le toluène et le 2,3,3-triméthylpentane peuvent coéluer. Si l’échantillon d’essence contient de l’isooctane (2,2,4-triméthylpentane) et du 2,3,4-triméthylpentane, il est probable qu’il contienne du 2,3,3-triméthylpentane. La concentration de 2,3,3-triméthylpentane est presque certainement inférieure à celle du 2,3,4-triméthylpentane. Lors du dosage du toluène et du 2,3,3-triméthylpentane, il est indispensable que l’intégrateur du chromatographe en phase gazeuse puisse mesurer les pics individuels, y compris ceux qui débordent du chromatogramme et ceux qui comprennent une droite verticale. Afin d’être décelables, le 2,3,3-triméthylpentane et le toluène doivent être présents dans un rapport d’au plus 5/1, l’un ou l’autre de ces composés pouvant être le plus concentré. Si ce rapport est supérieur à 5/1, il se peut que le toluène et le 2,3,3-triméthylpentane ne donnent qu’un seul pic sur le chromatogramme, le constituant le moins concentré étant alors intégré avec le constituant le plus concentré. Généralement, quarante composés de concentration supérieure à 1 % en masse représentent en moyenne 80 % de la masse de l’essence automobile. La présente méthode révèle, parmi ces quarante composés décelés dans l’essence, des pics de coélution pour le toluène, le 2-méthylhexane, le méthylcyclopentane et le n-hexane (voir le tableau A.1 de l’annexe A). Ces quarante composés sont indiqués au tableau 5 par l’apposition d’un astérisque au numéro d’identification. Le nombre de pics de coélution dépend du nombre total de composés individuels et du nombre de composés oléfiniques présents. La possibilité de coélution croît avec le nombre de composés détectés après le n-octane. D’autres techniques d’analyse, comme celles décrites dans l’ASTM D1319 pour les oléfines, dans l’ASTM D5580 et D5769, pour les constituants aromatiques, et dans l’ASTM D4815 et D5599 pour les constituants oxygénés peuvent aider à interpréter les données obtenues à l’aide de la présente méthode. La mise à l’essai et l’évaluation d’un produit en regard de la présente méthode peuvent nécessiter l’emploi de matériaux ou d’équipement susceptibles d’être dangereux. Le présent document n’entend pas traiter de tous les aspects liés à la sécurité de son utilisation. Il appartient à l’usager de la méthode de se renseigner auprès des autorités compétentes et d’adopter des pratiques de santé et de sécurité conformes aux règlements applicables avant de l’utiliser.

CEN ISO/TS 23973:2021 临界条件下的液相色谱（LCCC） 聚环氧乙烷的化学异质性（ISO/TS 23973:2020）

This document establishes a valid method for separation of chemically heterogeneous polyethylene oxide (PEO) mixtures and for the determination the number and content of the chemically heterogeneous species in the overall sample. The method presented in this document serves as a technical guideline and enables laboratories to learn the principle of "critical chromatography" on a validated system. This method presented in this document with its stated system parameters is not applicable for other polymer classes, due to the diversity of the interactions between the polymer/mobile phase/stationary phase and the number of separation systems that are therefore available. The evaluation of the interlaboratory testing has shown that many error sources relate to the technique of liquid chromatography in general. Possible error sources are described in Annex A. Details on the evaluation of the interlaboratory testing are given in Annex B. Elugrams of the participants (excerpts) are given in Annex C. Investigations of the long-term stability of the test mixture are given in Annex D.

ASTM E2143-01(2021) 使用现场便携式光纤同步荧光光谱仪对芳烃和多环芳烃现场样品进行定量的标准试验方法

1.1 This test method covers a rapid method for the screening of environmental samples for aromatic hydrocarbons (AHs) and polycyclic aromatic hydrocarbons (PAHs). The screening takes place in the field and provides immediate feedback on limits of contamination by substances containing AHs and PAHs. Quantification is obtained by the use of appropriately characterized, site-specific calibration curves. Remote sensing by use of optical fibers is useful for accessing difficult to reach areas or potentially dangerous materials or situations. When contamination of field personnel by dangerous materials is a possibility, use of remote sensors may minimize or eliminate the likelihood of such contamination taking place. 1.2 This test method is applicable to AHs and PAHs present in samples extracted from soils or in water. This test method is applicable for field screening or, with an appropriate calibration, quantification of total AHs and PAHs. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
