4. The accumulator piston delivers solvent, under pressure, to the vent
valve and the inline 22-µL filter.
5. From the inline 22-µL filter, the solvent flows to the ACQUITY UPLC or
Alliance flow-splitter.
6. The flow-splitter splits the solvent flow exiting the column into two
streams:
•
One stream is diluted with ISM solvent and diverted to the source of
the QDa detector.
•
The other stream is diverted toward the optical detector, undiluted.

Flow-splitter kit as
follows:
1. Solvent is degassed through the in-line vacuum degasser.
2. The solvent is filtered before entering the primary check valve.
3. The filtered solvent flows through the primary check valve and into the
piston chamber.
