Analysis Solutions for Gases and Very Volatile Compounds: PLOT Columns

The separation of compounds with very high vapor pressure (e.g., permanent gases, light hydrocarbons) can either be performed on polysiloxane liquid phases under cryogenic conditions or with PLOT columns.

PLOT (Porous Layer Open Tubular) columns offer a the more convenient alternative, mainly because they can be operated at above ambient GC oven conditions.

PLOT columns are based on porous particles that are fixated to the inner wall of the capillary tubing and compounds are separated based on their difference in surface interactions with the solid stationary phase.

In this webinar we will cover the principles of PLOT separations and discuss an array of separations including permanent gases, light hydrocarbon isomers, sulfur compounds and oxygenates on Agilent’s comprehensive portfolio of PLOT columns.
