Thanks for your reply.
The results are getting worse day by day means that sometime even if I follow the same procedure, I dont get the peak. I dont reuse the Polypropylene vials.But I do keep my stock solution in PP vial and have been using it from the same vial for a couple of weeks.( I think PFOA wont react with the PP material).
The liner that we use is glasswool based on my understanding. But I can be wrong....have to check it with my labmates. I didnt know that inlet temperature has a big role. I will make sure that it is the same as in the paper. The carrier gas is Helium with a flow rate of 1.0 ml/min.
Also does manual injection has any advantage over the autosampling in terms of accuracy or reducing the contamination or anything?
I do feel that I missed out so much details in my previous posts which make it hard for many of you to diagnose the problems...Sorry about that!
