固定污染源中氯乙烯测定辅助填充柱
固定污染源中氯乙烯测定辅助填充柱 详细信息：

名称：填充柱
规格：1.2m*3mm
粒度：80-100目
材质：不锈钢/玻璃
应用：HJ T34-1999固定污染源排气中氯乙烯的测定 气相色谱法

针对固定污染源排气中氯乙烯和丙烯醛进行测定,浩瀚色谱（山东）应用技术开发有限公司建立采用针筒采样、手动进样、GDX-105填充柱分离、FID检测器进行检测的方法。目标化合物峰形对称、分离度好,与其它干扰的化合物有较好的分离。氯乙烯和丙烯醛检出限为0.132 mg/m3和0.120 mg/m3,满足固定污染源排气监测要求,并在1~200 mg/m3范围内可以进行准确测定。对配制标气和用空气模拟的实际样品的测定,RSD均在5%以内。通过保存时间对浓度影响的研究,推荐采样24 h完成分析。

Auxiliary packed column for determination of vinyl chloride in stationary pollution sources
Auxiliary Packed Column for Determination of Vinyl Chloride in Stationary Pollution Source Details:

Name: Packed Column
Specifications: 1.2m*3mm
Granularity: 80-100 mesh
Material: Stainless Steel/Glass
Application: HJ T34-1999 Determination of vinyl chloride in exhaust gas from stationary pollution sources by gas chromatography

For the determination of vinyl chloride and acrolein in the exhaust gas of stationary pollution sources, Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. established a method of using syringe sampling, manual injection, GDX-105 packed column separation, and FID detector for detection. The peak shape of the target compound was symmetrical, the resolution was good, and it was well separated from other interfering compounds. The detection limits of vinyl chloride and acrolein were 0.132 mg/m3 and 0.120 mg/m3, which met the requirements for monitoring the exhaust gas of stationary pollution sources, and could be accurately measured within the range of 1 to 200 mg/m3. For the determination of the prepared standard gas and the actual sample simulated by air, the RSD is within 5%. Through the study of the effect of storage time on the concentration, it is recommended to sample for 24 hours to complete the analysis.
