I have a mixture of some unknown chemicals. e.g. Isophthalic acid, terephthalic acid, adipic acid or neopentyl glycol, 1, 6-Hexanediol, ethylene glycol etc.
In these mixture 1 component is measure while the other two are in very small quantity which I am not able to detect in NMR.
Can I find the small quantity via GC-MS? if yes, how to develop the method for the detection?
Please look at the following below links which may help you in your analysis:

Thanks
To develop a method for GCMS, the compound should should be soluble in suitable solvent. Usually liquids, low m.p.solids which vapourise on heating can very easily be analysed.You can match the spectrum with that availble in the computer compound library.
