We have a Scion/Bruker GC456, with a HeadSpace autosampler SHS-40. The GC has a FID detector.
We are injecting an OVIS STD. (We prepare it with Methanol, Ethanol, Acetone, IPA, Diethylamine, Ethyl Acetate, Triethylamine)
The problem here, is that after a weekend the amines started tailing much more than before.
We have trim the column, heat the HeadSpace valve an d transfer line, changed the liner, clean the injector and detector ports, changed the column.
Any one know what can be happening???
