I'm trying to develop a method for residual solvents(Methanol and Ethanol) in a solid sample. I am using HeadSpace Turbo matrix 16 coupled to GC HP6890 5973Mass Selective detector. I was using different methods that I have found online, but I don't get any signal.
MeOH and EtOH standards been made up in Water and 1ml of it been transfered to the Head SPsce vial, I heat it for 20 min at 80 degrees. If i'm running just water blank I get the same result,no differences. To me seems like there might be something wrong in the system, the tune evaluation looks perfect, no leaks.
I have checked the gas and looks alright through HeadSpace transfer line and I was running a standard using just the GCMS to see if there is any blockage in the system and I got poor sensitivity. Can someone advise me what might be the problem?
Thank you
