Effects of Water on Adsorbents in Porous Layer Open Tubular (PLOT) Column Gas Chromatography
The effects of water on retention and selectivity in gas–solid chromatography of various adsorbent PLOT columns is reviewed.
Effects of Water on Adsorbents in Porous Layer Open Tubular (PLOT) Column Gas Chromatography (GC)
Solid adsorbent gas chromatography (GC) columns, such as porous layer open tubular (PLOT) columns, are the best option for GC analysis of C1–C5 hydrocarbons, but water can affect retention and selectivity. We review the effects of water for different types of PLOT columns, and explain how to prevent or remediate the problem.
There is No Time to Waste: Low-Pressure Gas Chromatography– Mass Spectrometry is a Proven Solution for Fast, Sensitive, and Robust GC–MS Analysis
Low-pressure gas chromatography (LPGC)–MS should be the first option in many GC–MS applications to provide fast, sensitive, and robust analyses; and the installation, instrumentation, and implementation of LPGC is possible in any GC–MS system.
Changing from Helium and Nitrogen While Maintaining Separation Efficiency and Analysis Time
Wouldn’t it be nice if we could make nitrogen work for applications where helium is not an option?
