GB/T40263-2021 Textiles - Determination of short chain LV paraffin GC-790MS




GB/T40263-2021 Textiles - Determination of short chain LV paraffin GC-790MS Details:








Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses n-hexane as the extraction solvent, ultrasonic extraction, 0.45 μ M organic phase microporous membrane filtration, a method for the determination of short-chain lv paraffin in textiles or leather by gas chromatography-mass spectrometry was established. The column type was selected and the extraction conditions were optimized. The standard curve within the scope of study is linear with a correlation coefficient of 0.9995. The recovery experiments with different concentrations were carried out. The measured recoveries were 90.42%~94.22%, and the relative standard deviation was less than 10%. The method is simple, fast and sensitive, and the determination limit of di is 1.5 μ g/mL。
