Textiles - Determination of certain organic solvents Warning --- personnel using this standard should have formal laboratory work experience. This standard does not indicate all possible safety issues question. It is the user's responsibility to take appropriate safety and health measures and to ensure compliance with the requirements of the relevant state laws and regulations.

1 Scope

This standard specifies the use of gas chromatography - mass spectrometry (GC/MSD) or gas chromatography - flame ionization detector (GC/FID) determination Textiles in 9 kinds of organic solvents (see Appendix A) residual amount of the method. This standard applies to all kinds of textile products.

2 principle

Methanol in the ultrasonic bath to extract residual organic solvents in the sample, after concentration by volume gas chromatography - mass spectrometry or gas chromatography - hydrogen Flame ionization detector for detection, qualitative analysis based on retention time and/or mass spectrometry selected ions, external standard quantitative.

3 Reagents and materials

Unless otherwise indicated, all reagents used in the analysis are analytical grade or above purity reagents. 3.1 Methanol, after the test detected no organic solvent or other interfering substances exist. 3.2 methanol. Chromatographic purity. 3.3 organic solvent reference material. 3.4 Standard stock solution (1000mg/L).
