Virtually Particle-Free Rt®-Silica BOND Columns
17 August 2015

Porous layer open tubular (PLOT) columns are very useful to GC analysts working on a wide variety of applications, and the unique selectivity of PLOT columns makes them particularly good for separating gaseous compounds without cryogenic cooling. A common issue with most columns is instability of the porous layer leading to shedding of particles which impede flow. The Rt®-Silica BOND column gives the retention and capacity needed from PLOT columns, along with virtually particle-free and water-resistant operation. This application note explains how the column’s unique selectivity makes it ideal for analysis of hydrocarbons, halogenated compounds, and sulfur gases.
