Import and export of textiles in N, N- dimethylformamide and
N, N- dimethylacetamide Determination of GC-MS
1 Scope
This standard specifies the textiles N, N- dimethylformamide and N, N- dimethylacetamide Residues by Gas Chromatography - Mass Spectrometry
method.
This standard applies to the determination of textiles.
Principle 2
N samples extracted with methylene chloride residues in an ultrasonic bath, of N- dimethylformamide and N, N- dimethylacetamide, and concentrated to volume
After the sample solution by gas chromatography - mass spectrometry to detect the use of qualitative full scan detection, select ion external standard.
