Optional ISM kits
Several optional ISM kits provide for flow splitting and post-column addition.
The flow-splitter kits allow you to adjust the amount of analytical flow diluted
and diverted to the QDa detector. Four splitter kits are available, each specific
to a Waters instrument class:
•
ACQUITY
®
LC (UPLC
®
, H-Class, and I-Class) Flow-splitter kit
•
Alliance
®
Flow-splitter kit
•
ACQUITY UPC
2
® Dual-Detection Flow-splitter kit
•
ACQUITY UPC
2
® Triple-Detection Flow-splitter kit
The Post-column Addition kit is used to add additional liquid to the analytical
flow stream before it enters the QDa detector. This kit is compatible with
ACQUITY UPLC and Alliance systems.
Primary pump
Draws solvent, transferring it to the accumulator
pump and system as part of the serial flow design.
Run LED
Indicates the ISM status.
Sample manager
purge solvent
degasser chamber
(optional)
Degasses the purge solvent which then flows through
the sample manager.
Note:
Vacuum degassing can change the composition
of mixed solvents.
Seal-wash pump
The pump that circulates solvent, to keep the
actuators’ high-pressure seals free of contaminants.
Seal-wash waste
tube
Conducts seal-wash waste to a waste vessel.
Solvent selection
valve (optional)
A valve that allows selection of up to six different
solvents used isocratically.
Vent valve waste
tube
Tubing that vents solvent to waste during priming.
Vent valve
A valve that automatically switches to waste during
priming and a block position during the leak test.
