Not sure I'll get an answer to this one...

Any GC-MS users out there?

I'm a rookie trying to get to grips with the procedures involved and I'm following BS standards but they can be a bit sketchy on the details. I confused as to whether the concentration of the injection standard you add to your sample immediately prior to injection must be equal to the concentration of the injection standards added prior to the extraction of the sample. I'm assuming so but can't seem to find the literature to back up my assumption (ps. I haven't actually carried out any analyses yet)?

Hi EV, I've got a book on it called: GC/MS - A Practical User's Guide( by Wiley-Interscience) in .pdf ebook format. If you think it could be of any use, send me a PM and I'll e-mail you the book.

Wal, I don't even want to know how you get these things!
