BS EN ISO 15796:2008 气体分析.分析偏差的调查和处理

This International Standard specifies generic methods for detecting and correcting bias (systematic errors) of analytical procedures for the analysis of gases, using reference gas mixtures or reference analytical procedures, as well as for estimating the correction uncertainty. The main sources of (and parameters affecting) bias of analytical procedures are instrumental drift (time) and matrix interferences (matrix composition). Moreover, bias normally varies with analyte concentration. This International Standard therefore establishes protocols for  detecting and correcting drift for an analytical system of limited stability,  investigating and handling bias of a stable analytical system for a specified range of sample composition, which are intended to be used in method development and method validation studies, either separately or sequentially. This International Standard specifies procedures for two options, applicable to systematic effects, as follows: a) tracing the observed pattern of deviations and correcting for their effect, b) averaging over their effects and increasing the uncertainty, where normally the first option entails lower uncertainty at the expense of higher effort. For the convenience of the user, the methods specified in this International Standard are described for procedures of composition analysis, i.e. procedures for measuring the concentration of a specified analyte in a gas mixture. However, they are equally applicable to measurements of physico-chemical properties of a gas or gas mixture relevant to gas analysis, and translation into this subject field is straightforward.

ASTM E410-08 液态氯水分及残余物标准检测方法

This test method provides for the determination of moisture and residue in liquid chlorine. The concentration levels of these impurities are important factors in many commercial uses of liquid chlorine.1.1 This test method covers the determination of moisture and residue in liquid chlorine. Lower limits of detection of 10 μg/g based on a 150-mL sample are achievable. 1.2 This test method describes operations and special apparatus for sampling liquid chlorine from cylinders. Sampling other commercial facilities such as tank cars, barges, and storage tanks require special techniques of manipulation in filling sample cylinders for testing. If conditions and facilities are favorable, the analysis apparatus may be connected directly to these larger storage and transportation units and on-the-spot tests may be completed. 1.3 The analytical methods are empirical and are gravimetric. They are applicable to the determination of the residue and moisture content of commercial grades of liquid chlorine (condensed gaseous product). 1.4 Residue is defined as being those substances which remain in the sample flask after sample volatilization under the conditions of the test. Moisture is defined as the volatile substances evolved during volatilization and purging of the sample-residue flask and absorbed on the desiccant contained in the absorption tubes under the conditions of the test. Some of the volatile chlorinated hydrocarbons may also be evolved from the sample residue flask during purge and absorbed, thus contributing to the apparent moisture analysis value. 1.5 This test method may be used for determining the moisture content only of gaseous chlorine if suitable and appropriate modifications are made for sample measurement and calculation. 1.6 Review the current material safety data sheet (MSDS) for detailed information concerning toxicity, first aid procedures, and safety precautions. 1.7 The values stated in inch-pound units are to be regarded as the standard. No other units of measurement are included in this standard. 1.8 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. Specific hazards statements are given in Section 7.

ASTM E1131-08 用热重力法进行成分分析的标准试验方法

This test method is intended for use in quality control, material screening, and related problem solving where a compositional analysis is desired or a comparison can be made with a known material of the same type. The parameters described should be considered as guidelines. They may be altered to suit a particular analysis, provided the changes are noted in the report. The proportion of the determined components in a given mixture or blend may indicate specific quality or end use performance characteristics. Particular examples include the following: Increasing soot (carbon) content of used diesel lubricating oils indicates decreasing effectiveness. Specific carbon-to-polymer ratio ranges are required in some elastomeric and plastic parts in order to achieve desired mechanical strength and stability. Some filled elastomeric and plastic products require specific inert content (for example, ash, filler, reinforcing agent, etc.) to meet performance specifications. The volatile matter, fixed carbon, and ash content of coal and coke are important parameters. The “ranking” of coal increases with increasing carbon content and decreasing volatile and hydrocarbon, (medium volatility) content.1.1 This test method provides a general technique incorporating thermogravimetry to determine the amount of highly volatile matter, medium volatile matter, combustible material, and ash content of compounds. This test method will be useful in performing a compositional analysis in cases where agreed upon by interested parties. 1.2 This test method is applicable to solids and liquids. 1.3 The temperature range of test is typically room temperature to 1000 °C. Composition between 1 and 100 weight % of individual components may be determined. 1.4 This test method utilizes an inert and reactive gas environment. 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 is related ISO 11358 but is more detailed and specific. 1.7 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.

ASTM E1127-08 俄歇电子能谱学中的深度压形的标准指南

Auger electron spectroscopy yields information concerning the chemical and physical state of a solid surface in the near surface region. Nondestructive depth profiling is limited to this near surface region. Techniques for measuring the crater depths and film thicknesses are given in (1). Ion sputtering is primarily used for depths of less than the order of 1 μm. Angle lapping or mechanical cratering is primarily used for depths greater than the order of 1 μm. The choice of depth profiling methods for investigating an interface depends on surface roughness, interface roughness, and film thickness (2). The depth profile interface widths can be measured using a logistic function which is described in Practice E 1636.1.1 This guide covers procedures used for depth profiling in Auger electron spectroscopy. 1.2 Guidelines are given for depth profiling by the following: Section Ion Sputtering 6 Angle Lapping and Cross-Sectioning 7 Mechanical Cratering 8 Mesh Replica Method9 Nondestructive Depth Profiling 10 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 problems, 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.

This Technical Report describes a method for determining ion-sputtering rates for depth profiling measurements with Auger electron spectroscopy (AES) and X-ray photoelectron spectroscopy (XPS) where the specimen is ion-sputtered over a region with an area between 0,4 mm2 and 3,0 mm2. This Technical Report is applicable only to a laterally homogeneous bulk or single-layered material where the ion-sputtering rate is determined from the sputtered depth, as measured by a mechanical stylus profilometer, and sputtering time. This Technical Report provides a method to convert the ion-sputtering time scale to sputtered depth in a depth profile by assuming a constant sputtering velocity. This method has not been designed for, or tested using, a scanning probe microscope system. It is not applicable to the case where the sputtered area is less than 0,4 mm2 or where the sputter-induced surface roughness is significant compared with the sputtered depth to be measured
