Причина отмены This practice describes the techniques used to inject whole paint samples directly into a gas chromatograph to obtain a chromatogram from which the solvent composition may be established.

Formerly under the jurisdiction of Committee D01 on Paint and Related Coatings, Materials, and Applications, this practice was withdrawn in June 2019 and replaced by Test Method D6886 on Determination of the Weight Percent Individual Volatile Organic Compounds in Waterborne Air-Dry Coatings by Gas Chromatography.1 This standard is being withdrawn because it: 1) lacks quantitative analysis, 2) references antiquated technology (for example, chart recorders, packed GC columns), 3) does not support mass spectrometry detection, and 4) is missing critical information, such as recommended column type, solvent type, internal standard, instrument conditions, and lacks a detailed sample preparation procedure.

Значение и использование

4.1 Gas chromatographic separation of solvents present in whole paints is the preferred first step for identifying and quantitating solvent compositions, using auxiliary procedures and techniques.
