I am working on Varian 450 GC having Galaxy software with PFPD (Pulsed flame photometric detector).
I am working on sulfur mode and i am trying to analyze Ethyl mercaptane in the LPG ( normally it is added in LPG near about 20 ppm).
I am collecting the LPG from cylinder to a 2 Ltr. taddler bag and analysing it through sample loop.
I am getting four peaks of sulfur ( after Ethyl mercaptan retention time i am getting three more peaks)
When i am injecting blank of helium from the same poly bag i am not getting sulfur peaks.
I just need help to understand why i am getting the four peaks of sulfur in LPG.
