Restek GC PLOT Columns

Traditional PLOT columns often result in variable coating thickness because of the difficulty in depositing particles in a homogenous layer.  This can lead to restriction and cause significant variation in gas flow.  Restek has developed technology and procedures to manufacture PLOT columns with concentric stabilized adsorption layers. These next generation PLOT columns show a constant flow behavior and have significantly improved mechanical stability, resulting in easier operation, better chromatography, and reduced particle release. Greater particle stability means more reproducible retention times, virtually no spiking, and longer column lifetimes. This innovative Restek stabilization chemistry is currently applied to all fused silica and metal PLOT columns.
