Agilent HP-Chiral GC Columns

Agilent J&W HP-Chiral ß columns have a chiral stationary phase based on permethylated beta-cyclodextrin, which has very broad applications for resolving volatile optical isomers. Beta-cyclodextrin is dispersed in a phenyl-based polymer. This polymer provides low bleed and will not interfere with nitrogen-specific detectors such as the nitrogen phosphorus (NPD) detector, allowing optimized sensitivity for chiral compounds containing nitrogen.

A 7 inch cage is the most common GC column format, compatible with Agilent 5890, 6890, 7820, 7890, 8860, and 8890 series GC systems, and all non-Agilent GC systems with a similarly sized oven. The 5 inch cage format is designed for smaller GC ovens e.g. for the Agilent GC 6850.
