What have you done for your HPLC (or GC or MS) today?
I'll start: On my $300 eBay refugee Waters 996 photodiode array detector (that's been running without a hiccup for a year), I've replaced the flow cell gaskets & lenses, the L1 beam splitter, the M1 mirror, the lamp, and the little foam filter media thingy. I've aligned the mirror, checked the lamp energy & wavelength accuracy, then run all onboard diagnostics. While doing this, I found a screw with crossed threads holding in the M1 mirror; now repaired.
The lamp energy quadrupled from where it had been, all onboard diagnostics passed, and wavelength accuracy was spot on.
Now to qualify the beast.
