名称：填充柱
规格：1.5m*4mm
型号：2%OV-17/Chromosorb W 60-80目
应用： GBZ/T 160.33-2004工作场所空气有毒物质测定 硫化物二硫化碳

浩瀚色谱（山东）应用技术开发有限公司建立气相色谱-三重四级杆串联质谱(GC-MS/MS)测定空气中痕量二硫化碳的方法。方法色谱柱为2%OV-17/Chromosorb W 60-80目,采用多反应监测(MRM)扫描模式,研究其优化条件。结果二硫化碳在检测范围内其响应值与浓度有较好的线性关系,相关系数达到0.999 4以上。该方法的低检测浓度为0.02 mg/m~3,相对标准偏差为0.4%~2.1%,加标回收率为88.3%~104.5%。结论所建立的方法解决国标火焰光度检测(FPD)或质谱(MS)方法干扰严重、响应低、线性范围窄的问题,可用于空气中痕量二硫化碳快速定性和定量分析。

Determination of Toxic Substances in Workplace Air CS2 Sulfide
CS2 Sulfide Determination of Toxic Substances in Workplace Air Details:

Name: Packed column
Specification: 1.5m*4mm
Model: 2%OV-17/Chromosorb W 60-80 mesh
Application: GBZ/T 160.33-2004 Determination of Toxic Substances in Workplace Air Sulfide Carbon Disulfide

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. established a gas chromatography-triple quadrupole tandem mass spectrometry (GC-MS/MS) method for the determination of trace carbon disulfide in the air. Methods The chromatographic column was 2%OV-17/Chromosorb W 60-80 mesh, and the multi-reaction monitoring (MRM) scanning mode was used to study its optimized conditions. Results The response value of carbon disulfide has a good linear relationship with the concentration in the detection range, and the correlation coefficient is above 0.999 4. The minimum detection concentration of this method is 0.02 mg/m~3, the relative standard deviation is 0.4%~2.1%, and the recovery rate of standard addition is 88.3%~104.5%. Conclusion The established method solves the problems of serious interference, low response, and narrow linear range of national standard flame photometric detection (FPD) or mass spectrometry (MS) methods. It can be used for rapid qualitative and quantitative analysis of trace carbon disulfide in the air.
