Maybe most. Certainly not ALL.
I personally went and replicated the “there is methanol in our gas?!?”…and posted the chromatogram within 24hrs of @Dukejohnson’s initial report.
Because you’re absolutely correct: if it can’t be REPLICATED it isnt science…
Much easier to ID an “unknown” if some other bugger gives you a clue where to look…
I’m working on obtaining a diethanolamine standard.
All I have is a GC fid, GC MS/MS would be more convincing.
I have convinced our third party lab to dig deeper into a dozen or so of our samples….now I’ve got to figure out which ones I want them to look at.
In my case we obtained tedlar sample bags, and added a sampling port to the system.
Samples are taken before loading gas into system, and/or from the working solvent IN the system.
I set this up (and documented it here for the rest of the class) BEFORE we started having fast crash issues.
Mainly to watch our solvent blend…
Do you have any analytics?
