PAHs analysis

[tsuihoping]

Dear all,

Is there anyone has the experience in analysing PAHs content in plastic and rubber? We found that there is a large matrix effect that made the quantification impossible. We use DCM : Hexane as our clean-up method. Is there any other method available?

Thanks in advance!

Best regards,

For these kind of matrixes, I have a very good experience trying dynamic headspace or thermal desorption.

If you have these stuff available, I would try it!
