evening bump.
at that price it might even be worth it to send it back to @srihugh1 for another column & injector.
I really like the packed column SRI sends with the 310MM for residual solvents.
At least in distillates and isolates.
I use the MXT-500 for anything high in terpenes because some of them take hrs to make it through the Hayes Sep D …others don’t seem to come out at all, and I haven’t moved the backflush @srihugh1 installed for me to that column yet. still working out how to use it with MCT on the MXT-500 correctly.
