摘要
本文简介了西门子色谱仪在全密度聚乙烯装置中的应用,重点介绍了改造样品定量管,并提出了一种方法:增大进样体积以提高TCD检测器对极低浓度H2的准确检测,保证循环气控制系统的H2测量准确性。
This paper introduces the the transformation of sample loop detection of very low concentration accuracy. application of Siemens chromatograph in full density polyethylene plant,emphasizes and provides one method：increase the volume of sample in order to increase the of H2 TCD detector,to ensure he control system of circulating gas H2 measurement
