Determination of 1,2-dichloroethane in blood samples by gas chromatography-mass spectrometry

Stationary phase: 5% phenyl-methyl polysiloxane
Specification: 60m*0.25mm*0.25um
Model: HH-5
Application: GBZ/T 286-2016 Determination of 1,2-dichloroethane in blood by gas chromatography-mass spectrometry

Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. established a gas chromatography-mass spectrometry method for the determination of 1,2-dichloroethane (1, 2-DCE) in blood samples. The method uses static headspace analysis, 1, 2 in the sample. -DCE was separated by HH-5 elastic capillary column and detected by gas chromatography-mass spectrometry. 62 mass-to-charge ratio (m/z) was selected for ion quantification, and 49, 98 m/z was confirmed to determine 1,2- in the blood sample. DCE. Results The linear relationship between 1,2-DC in 0.63～93.98μg/L was good, the correlation coefficient was 0.999 7, the lower limit of quantification was 0.63μg/L (take blood sample 2.0 ml). The relative standard deviation (RSD) in the batch was 2.9%～6.7%, the RSD between batches is 3.4%～8.1%, the recoveries of standard addition are 83.2%～94.1%, and the samples can be stored for 7d below -8°C. Conclusion The method has high sensitivity, less interference, precision and accuracy. Good, easy to operate, easy to popularize, can be used as a method to detect 1,2-DCE in blood samples of occupational poisoning patients.
