Hello!
I'm really newbie in GC/MS analysis. I want to carry out a SPME extraction using a CAR/DVB/PDMS fiber.
I conditioned it at 270C for 1h as suggested in the instructions, but I still haven't a "blank", I mean I still have a lot of peaks whose spectra are identified as siloxanes or silanes, so clearly due to a fiber release.
Have anyone had a similar problem?
Do I need to repeat the conditioning step or do it for a longer time?
Thanks!
