GCMS
Default GCMS Configuration: SPL-GCMS Always order 0.25mm I.D. column. Avoid using twin line. Dual monitors is highly recommended, triple is not bad, but I think most of user cannot master them. Consumable: Aluminum Oxide, SZ-220-94606-00, 4 Oz. Abrasive paper Interesting Options: AFT: either detector splitting or detector switching system. Add a GC detector to work with MS at the same time. For option to remove column without vent: Restek 22431 for regular fused silica column Frontier Lab Vent-Free GCMS adapter for metal column. Hydrogen as carrier gas: Hydrogen sensor is highly recommended. It can detect hydrogen leaking inside GC oven. Hydrogen can be vent into room by these paths, connect those to fume hood to get rid of H2. septum purge split vent. rough pump exhaust. Hydrogen may saturate pi bond for VOC. Hydrogen may split SVOC internal standard peak.
