Hello there,
I was wondering if anyone in the subreddit had any procedures on extracting compounds from things like propylene glycol or glycerine? I have tried using DCM and salt water for PG extractions to poor results (I think the instructions I was provided might just suck though).
The compounds of interest in the samples I am running have colluding peaks of with both solvents, so even just turning off the MS during these peaks means im leaving things out.
If you guys have any suggestions id love to hear them!
Equipment and current method:
Agilent 7890A and 5975C
ZB-Waxplus
1:100 split injection, 1uL injection amount with 2-4 second viscosity delay
Ti = 75 c, hold for 1.5min (solvent delay), 10c/min to 155, hold 1 min (ms is off during this time too), 10c/minute to 250
Edit: I just realized I do have access to a fumehood and a distillation set up, if this helps anyone with suggestions.
