ChromaBLOGraphy: Maximum temperatures of packed columns – Sulfur Gases
For my fifth and final post in this series, I would like to focus on packed columns for light sulfur gases. Compounds include (but not limited to) hydrogen sulfide, sulfur hexafluoride, carbonyl sulfide, sulfur dioxide, methyl mercaptan, ethyl mercaptan, etc. Because some analysts prefer PTFE tubing and/or PTFE frits for their columns, the maximum temperature […]
Author: Jaap de Zeeuw Restek Corporation Published By: J. Sep. Sci. Year of Publication: 2016 Link: http://www.sepscience.com/Bespoke-Products-List?pgid=115&artid=4442 Abstract: Sulfur components are widely present in many raw materials used for hydrocarbon processing. The sulfur components are undesirable because they have a strong smell, … Continue reading

ChromaBLOGraphy: Two Detector Solution to Analyzing Sulfur
Dan Li, Katarina Oden, Chris English, and Jason Herrington Sulfur compounds are reactive, corrosive to pipes, and destructive to catalysts in petroleum refineries. Sulfur emission are strictly regulated globally. When released into the atmosphere sulfur dioxide converts to sulfuric acid resulting in adverse effects on human health and the environment. Sulfur detection is found useful […]
