Please could somebody let me know if the following set up is correct:
Outlet A from degasser to inlet D on pump
Outlet B from degasser to inlet A on pump
Outlet C from degasser to inlet B on pump
Outlet D from degasser to inlet C on pump

Hi,
Outlet from the degasser goes to the respective Letter A to A and so on. Output from degasser goes to GPV. So lines needs to be in sequence the correct sequence. Hope this helps.
Regards,
Bull76.

Right, from degasser connects to the multi-channel gradient valve.
Please could somebody let me know if the following set up is correct:
Outlet A from degasser to inlet D on pump
Outlet B from degasser to inlet A on pump
Outlet C from degasser to inlet B on pump
Outlet D from degasser to inlet C on pump
Thanks

For the most part, it doesn't matter how you arrange the lines from the degasser to the proportioning valve. It's simpler for everyone involved if you keep A to A, B to B, etc. Agilent has some advice about using particular mobile phases like buffers with the quaternary pump, though. See page 32 and 37 of the following document:

CPG was that really necessary
He's the "direct" one on this board. But he seems to know his stuff.

I don't believe CPG was the only person who may have expressed something akin to "What the hell is that?" when they read the OP's description of their setup. However, I've seen enough "this works so be quiet about it" setups in my time to be judgmental anymore. Like I said before, the pump cares not what the degasser does, or vice versa. But simplicity dictates A-A, B-B, etc. Otherwise, you're left with "I think there's something wrong with the A solvent, which is actually the B solvent, so let's replace the B solvent to fix the problem with the A solvent" which gave me a headache just writing it.
