GC Analysis of Sulfur Components in Propylene Using a Pulsed Flame Photometric Detector
摘要
Abstract
The Agilent JW Select Low Sulfur column used in a GC with a sulfur-specific detector, such as a PFPD, can detect H2S, COS, and CH3SH at trace levels in a propylene matrix as a result of effective separation of the sulfur compounds and the matrix. Separating the matrix from the sulfur components eliminates the quenching effects caused by the matrix, and gives a better response for the sulfur compounds. The column provides a good response for reactive sulfur compounds, such as H2S, which makes detections of 20 ppb possible. Although this is a PLOT column, no spikes will be observed because the column does not shed particles. It can therefore be used safely in combination with valves.关键词
