Would you be able to walk us through why lower pollution temperature matters so much when your analytes are explosives?
Chris FreyeGUEST
So the gold standard for explosives analysis for the longest time and still is LC, right? We don't have any issues with compounds breaking down.
Chris FreyeGUEST
Now we do sometimes have issues with detection, with ionization in our ESI source or APCI source.
Chris FreyeGUEST
And interestingly enough, I've actually seen explosives ionize themselves in an APCI source, which was really weird when you get with unnormal adducts.

I'm curious to hear how that idea originated and what does it let you see that a separate oven aging study wouldn't?
