Model: HH-624

Specification: 30m*0.32mm*1.8um
Application: GB/T 37633-2019 Textiles Determination of 1,2-dichloroethane, chlorohydrin and chloroacetic acid

Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. established a method for the determination of 1,2-dichloroethane in textiles by gas chromatography-mass spectrometry (GC-MS). After ultrasonic extraction of methanol, HH-624 (30) m*0.32 mm*1.8 μm) is a chromatographic column, which is characterized by gas chromatography-mass spectrometry combined with full scan and selective ion scan for qualitative and quantitative analysis and external standard method. The results show that: in the range of 0.05-30 mg/L, 1, The linear relationship of 2-dichloroethane is good, the correlation coefficient is 0.999 3; the detection limit of the method is 0.50 mg/kg. At 0.5, 1.0, 5.0 mg/kg 3 spiked levels, viscose, polyester, wool The recoveries of the seven textile substrates of nylon, mulberry, acrylic, and cotton were 85.2% to 101.4%, and the relative standard deviation (RSD) was 4.0% to 7.4%. The method is simple, accurate, and has high sensitivity and precision. Suitable for the analysis and detection of 1,2-dichloroethane in textiles.
