Something that may be a problem I had happen one time is that they gave me 70/30 isobutane/propane, and the sticker said butane , but the small sticker said iso…
It caused higher pressure and a loss of solvent until I figured it out, and it was still fucked.
Also, if you aren’t using nitrogen, then I can see you losing a lot of solvent in the columns
how do you pressure check your system before each use?
He obviously doesn’t and hasn’t ever (properly) pressure checked his system if he doesn’t have nitrogen on hand.
