在气相色谱分析中采用Agilent J&W低硫选择性色谱柱及硫特异性检测器如脉冲火焰光度检测器(PFPD),可将含硫化合物从基质中高效地分离出来,因而可对丙烯基质中痕量H2S,COS与CH3SH进行检测。将含硫化合物从基质中分离出来再检测,可避免基质引起的抑制效应并提高含硫化合物的响应。该色谱柱为活性含硫化合物如H2S提供了较好的响应,使含量低至20ppb的检测成为可能。尽管这是一种多孔层开管柱(PLOT),但它不会出现颗粒物质脱落现象,色谱图无锐峰。因此,与阀结合使用是安全的。
Sulfur-containing compounds can be efficiently separated from the matrix by GC with Agilent J & W Low-sulfur Selective Columns and sulfur-specific detectors such as pulsed flame photometric detectors (PFPD) in gas chromatographic analysis, The amount of H2S, COS and CH3SH testing. Separation of sulfur compounds from the matrix and then detected to avoid matrix-induced inhibitory effect and improve the response of sulfur compounds. The column provides a good response to active sulfur-containing compounds such as H2S, making the detection as low as 20 ppb possible. Although this is a PLOT, it does not shed particles and shows no sharp peaks. Therefore, it is safe to use with the valve.
