Suzan,

Each column manufacturer will have a comparable column with similar
coating, and generally speaking all would meet the needs of the gas bench
application. I'm partial to the GSQ from J&W (now Agilent) because the
bonded phase is more stable than from other companies. That, however,
shouldn't be a huge issue in the GasBench, where the system isn't normally
fiddle with.
