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.
