I'm in a printing ink industry. We use to analyse resin system and solvent system using GC-FTIR. We use GC to detect solvent composition and FTIR to find Resin composition and then we use to calculate the percentage of the resin from the FTIR graph. If we use GC-MS then how it will be benefitted for us?

Please, I would like to know the appropriate column used for the analysis of glycerol especially the unreacted glycerol from the liquid mixture of steam reforming of glycerol? Secondly, DB Wax UI columns have been suggested for the analysis of glycerol, however, the maximum temperature limits for these columns are 260 and 250 C for 0.25 um and… (Show more)

Hello,   I am missing the snapshot function, from the old Chemstation.   Is there a way, to get any information about the currently running sample out of the system ?   Or do I have to wait, till the sequence is finished.     Thank you.

I'm writing an assignment on fatty acids in Chia seed oil, and to that i'm using GC But when i try to identify the 5 components (C16:0, C18:0, C18:1, C18:2, C18:3) it keeps showing an extra peak that shouldn't be there. I tried to make a standard solution with only C16:0 in order to identify it, but the extra peak just keep showing up.   Column:… (Show more)

I want to determine the concentrations of CO, CO2 and H2 in syngas samples using mass spectrometry as I currently do not have the right GC column for it. Is it possible to do this? Can anyone guide me with the protocol for this? My setup consists of a GC column (HP-5). I will be manually injecting the samples and they have to pass through the… (Show more)
