Typical GUARANTEED GROB Test Report(s) PDFMEGA-WAX; MEGA-5MSFAST; MEGA-5
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 to out your GC System
Almost invariably any loss of performance can be firstly attributed to contaminiation 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
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
