This is part of the wholesale price list for "Nammex", the supplier of mushroom powders that many companies repackage/encapsulate and sell for a huge profit margin

Were you not previously testing for solvent residue?

When something popped up in IR and NMR data that we could not ID, yes. Then we would do residual solvent analysis to confirm if those were the signals, and at what concentration. However, not every batch. We didn't have an in-house gas chromatograph till a couple weeks ago. We had to send off for residual solvent testing, and that's a lot of money to spend if you don't see any indication of residuals in IR or NMR data. We would also send off if there was a smell we couldn't ID. The human nose can pick up ppb range of volatile solvents. It's a pretty damn good detector.
I don't imagine we are going to catch too much, based off past data. However, I want to have as much data as we can possibly get, and we needed a GC in our lab anyway. We are also using the GC for other analyses, like alpha-GPC. That one you can't HPLC/UPLC. You have to test it with a gas mobile phase. Fish oil is the same. You GC for fatty acid and omega-3 content. Till this point we always had to send out for those. Now we can start doing them in-house!
