I am not an expert on this but I thought I would suggest at least one article on the subject; "Headspace analysis of some typical organic pollutants in drinking water using differential detectors: effects of columns and operational parameters" Mehran, M.F., Golkar, N., Cooper, W.J., Vickers, A.K., Jrnl of Chrom. Science, V34, March 1996, P. 122. Talks about the use of headspace with ELCD, PID and ECD with headspace sampling.

Good luck, hopy you get more responses.
