ISO 6142:2001 气体分析 标定用混合气体的制备 称重法

This International Standard specifies a gravimetric method for the preparation of calibration gas mixtures in cylinders of which the target accuracy of the composition has been pre-defined. It is applicable only to mixtures of gaseous or totally vaporized components which do not react with each other or with the cylinder walls. A procedure is given for a method of preparation based on requirements for the final gas mixture composition to be within pre-set levels of uncertainty. Multi-component gas mixtures (including natural gas) and multiple dilution mixtures are included in this International Standard and are considered to be special cases of the single component gravimetric preparation method. This International Standard also describes the procedure for verifying the composition of gravimetrically prepared calibration gases. Provided rigorous and comprehensive quality assurance and quality control procedures are adopted during the preparation and validation of these gravimetric gas mixtures, calibration gases of the highest accuracy can be obtained for a wide range of gas mixtures, in comparison with other methods of preparing such gases.

ASTM E1386-00(2005) 用溶剂萃取法分离和浓缩从火烧瓦砾样品中获取的可燃液体残渣的标准实施规程

This practice is useful for preparing extracts from fire debris for later analysis by gas chromatography, GC/MS, or GC/IR. This is a very sensitive separation procedure, capable of isolating quantities smaller than 1 μL of ignitable liquid residue from a sample. This practice is particularly useful when the potential for fractionation during separation must be reduced, as when attempting to distinguish between various grades of fuel oil. This practice is particularly useful for the extraction of nonporous surfaces such as glass, or the interior of burned containers. It is also particularly well suited to the extraction of materials from very small samples. This practice can be hampered by coincident extraction of interfering compounds present in the fire debris samples. This practice may not be useful for the extraction of some Class 0 and Class 1 ignitable liquids, which may evaporate during the concentration step. This is a destructive technique. Whenever possible, this technique should only be used when a representative portion of the sample can be reserved for reanalysis. Those portions of the sample subjected to this procedure may not be suitable for resampling. Consider using passive headspace concentration as described in Practice E 1412.1.1 This practice covers the procedure for removing small quantities of flammable or combustible liquid residue from samples of fire debris using solvent to extract the residue. 1.2 This practice is suitable for successfully extracting flammable or combustible liquid residues over the entire range of concentrations. 1.3 Alternate separation and concentration procedures are listed in Test Method E1387. 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 and health practices and determine the applicability of regulatory limitations prior to use.

1.1 This test method covers the determination of total carbonyl in the range from 0.5 to 50 ug calculated as CO.1.2 This test method is intended to be general and does not include steps for sample preparation.1.3 Acetals that hydrolyze under the conditions of the test are also determined.1.4 Carbonyl derivatives such as acetals and imines that are easily hydrolyzed may be determined by an alternative procedure.1.5 The developed color is not stable and must be measured within a specified period. Note 1--Other test methods for the determination of traces of carbonyl compounds are given in Test Methods D1089, D1612, D2119, and D2191.1.6 Review the current appropriate Material Safety Data Sheets (MSDS) for detailed information concerning toxicity, first aid procedures, and safety precautions.1.7 The values stated in SI units are to be regarded as the standard.1.8This 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 and health practices and determine the applicability of regulatory limitations prior to use. Specific hazards statements are given in Note 4 and Section 8.

ASTM E1385-00 用蒸汽蒸馏法分立和浓缩从火烧瓦砾样品中获取的可燃液体残渣的标准实施规程

Steam distillation is a classical separation technique, useful for preparing extracts for analysis by gas chromatography GC/MS or GC/IR. Distillates are suitable for analysis according to Test Method E 1387 or Guide E 1618. The visible oily liquid extract can be used as a courtroom exhibit, unlike extracts produced by other separation procedures which are solutions rather than a neat liquid. This practice is not useful for the separation of water soluble ignitable liquids such as alcohols or ketones. Alternate separation and concentration methods are suggested if the concentration of flammable or combustible liquid residues is not detectable by odor. This is a destructive technique that should only be used when a representative portion of the sample can be reserved for reanalysis. Those portions of the sample subjected to this procedure may not be suitable for resampling. Consider using passive headspace concentration as described in Practice E 1412.1.1 This practice covers the procedure for separating visible quantities of water insoluble hydrocarbons from samples of fire debris. 1.2 This practice is recommended only for samples which have a detectable odor of petroleum distillates when examined at room temperature. 1.3 This practice can yield useful extracts by the application of a solvent to the distillation trap in the event that only small quantities of hydrocarbons are obtained. 1.4 Alternate separation and concentration procedures are listed in the referenced documents. 1.5 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 and health practices and determine the applicability of regulatory limitations prior to use.

1.1 This practice covers the procedure for removing small quantities of ignitable liquid residue from samples of fire debris using an adsorbent material to extract the residue from the static headspace above the sample, then eluting the adsorbent with a solvent. 1.2 While this practice is suitable for successfully extracting ignitable liquid residues over the entire range of concentration, the headspace concentration methods are best used when a high level of sensitivity is required due to a very low concentration of ignitable liquid residues in the sample. 1.2.1 Unlike other methods of separation and concentration, this practice is essentially nondestructive. 1.3 Alternate separation and concentration procedures are listed in the referenced documents. (see Practices). 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 and health practices and determine the applicability of regulatory limitations prior to use.
