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 […]

ChromaBLOGraphy: Selecting the best column for Speciation of Sulfur Compounds in Natural Gas

Last Pittcon conference, a poster was presented based on some recent  work done by Rick Morehead from our applications laboratory in Restek Bellefonte. The focus was sulfur speciation in natural gas, Sulfur gases were tested up to tetrahydrothiopene. Natural gas is a complex mixture of low molecular weight hydrocarbons, inert gases and other impurities including [...]

ChromaBLOGraphy: When NOT to use (GC) Mass Spec

We often get asked in tech service for a column recommendation for a specific analysis, but before we provide an answer, we ask what GC detector is going to be used. This is important to know because certain dimension columns work better with certain detectors. I tried to elaborate on this topic in one of [...]

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 […]
