Priming the binary gradient module
To prime the binary gradient module:
1. On the front panel, press the Prime button. This action pulls solvent
through the four pump heads, primes the A1 and B1 solvent inlet tubes,
and then primes the pump.
2. To prime other solvent inlet tubes or modify solvent flow rates, in the
MassLynx inlet status page, select the Additional Status tab, and then
select the Chroma button.
3. In the Diagnostics Chromatographic Pump dialog box, select Diagnostics
> Wet Prime.
