Collection: Gas Chromatography PLOT Columns
Gas chromatography PLOT (Porous Layer Open Tubular) columns are purpose-built for the efficient separation of permanent gases, light hydrocarbons, and volatile compounds that are difficult to retain on conventional capillary columns. Featuring a porous adsorbent layer bonded to the inner wall of the column, PLOT columns deliver exceptional retention, sharp peak shapes, and reliable separation of low-molecular-weight analytes such as CO₂, CO, methane, ethane, propane, and light olefins.
