This document describes the GC analysis of sulfur components in propylene using a Pulsed Flame Photometric Detector (PFPD). The analysis method allows for the measurement of trace levels of target components in C3 hydrocarbon streams without any matrix interference.
The document details a Gas Chromatography (GC) method for quantifying trace levels of hydrogen sulfide, carbonyl sulfide, and methyl mercaptan in light hydrocarbon streams. It addresses the issue of matrix interference and quenching effects caused by large sample volumes when using sulfur-specific detectors like the Pulsed Flame Photometric Detector (PFPD).
The study utilizes the Agilent J&W Select Low Sulfur capillary PLOT column, which features a novel stationary phase designed for high loadability and unique selectivity. The method successfully separates sulfur species from the propylene matrix, eliminating quenching effects and allowing for detection at low parts per billion (ppb) levels.
The column provides detections of 20 ppb for reactive sulfur compounds such as hydrogen sulfide.
No, no spikes will be observed because this column does not shed particles.
