J&W GC Columns

Gas Chromatography (GC) columns are at the heart of the gas chromatograph and responsible for the separation process. GC is one of the most important and critical tools in analytical chemistry, because of its effectiveness, sensitivity and ease-of-use. GC columns contain a stationary phase, typically a polymeric material. It is through the interaction between the analytes and this stationary phase within the column that separation of the analyte into their molecular components can occur.

There are two types of GC columns: packed columns and capillary columns. Agilent offers over 3500 J&W GC columns. GC column types include fused-silica capillary wall-coated open tubular (WCOT), porous-layer open tubular (PLOT), and packed columns with the best inertness for acids/bases/mixed functional compounds, the lowest bleed levels and tightest column-to-column reproducibility.

The new J&W 5Q columns combine industry-leading Ultra Inert performance with Ultra Low-Bleed technology, delivering the new standard for GC/MS column performance and productivity.
