High(est) Performance Guaranteed Inertness Columns : tested with Grob Test Mixes
Test Mix Ampoule supplied with each Column
We recommend on initial columns installation you immediately run GROB’s TM to establish a “base-line” column performance AND to test out your overall GC System
Almost invariably any loss of performance can be firstly attributed to contamination of the Injection Port Liner, column connection ( graphite ) Ferrule particles or even shards of column outer polyimide bridging column end )
Do NOT exceed MAX recommended Column Temperature for each phase.
Use an OxyTrap on ALL GC Columns ( particularly polar columns /eg CarboWAX) if used at > 120degC else oxidation of phase cause peak tailing and extreme base-line drift !
