Like, I'm figuring it out. But I've been deep in method implementation and development for a simple reverse phase GCxGC (with recommended parameters!) for a while now, and finally making progress. But when I looked at my notes I realized it's been a solid month of work to get here - first tests were 28 Oct. That's atypical for me, either it's a lazy month to implement a chromatography method, because I'm working on something else, or (more likely) a few hours or days to implement and validate.
