Hi, I want to identify the solvents found in glues using GC-MS, but havent got a proper method to do that. does anyone have an idea how to go about it?

First try headspace or SPME.

I'd first try some sample in a closed septum vial, heat to maybe 100 C, use SPME or headspace; I'd start GC at 40 C and program to at least 250 C, you'll see solvents
