I'd have to look at my 1260, but in the column heating compartment there's two separate 6-port valves.. I'm pretty sure you can set it up to have one column plumbed to work with each set.
For the fraction collector, pre--label your tubes. We use Avery clear return address labels and pre-print them.
Hope that helps!
I like the label suggestion. But now that I think about it, should I have two fraction collectors? Is that possible?
Thanks. - Max
You can do this on a 1260 with a switch valve - even up to 8 columns!
You link the name of the column to the method. You can track down which column you used with which method. The fraction collector doesn't care which column used, but it knows which method you used.
With the new 1260 Infinity II you can have two separate temperature controlled compartments, thus up to 16 columns.
