I'm trying to run calibration curve for propylene glicol without success..
Using 5975C MSD, 7890A with Gerstel MPS.
I'm using headspace technique.
Enclosed is the method I'm running.
Would really appreciate any comments
Hi Has this method worked before on this instrument or another instrument?
I do get the propylene glycol peak but response is not correlated to concentrations
So the response is not linear, correct. Is it bouncing all over the place or dropping off at high end?
I was never able to do glycols via headspsce in the past. The only way I was able to do them was direct injection and FID. 5890 using megabore column.
Maybe you could try SPME.
