Sample Loop
The ProStar 400 is factory-equipped with a 20 µL sample loop.
If a different volume is to be injected, the sample loop must be
replaced. Please note that to fill the loop quantitatively, three
times the loop volume is withdrawn from the sample vial for
loops smaller than 100 µL and twice the loop volume for loops
larger than 100 µL.
Loops ranging from 5 µL to 1 mL are available from Varian.
Digital Dispenser System (DDS)
The DDS pump tubing cassette is factory-installed and
connected to the injection valve. Fasten the pump tubing
cassette before use with the screw on top of the pump tubing
cassette. If the AutoSampler is not to be used for two days or
more, be sure to loosen this screw to prevent permanently
deforming the tubing. If the pump tubing cassette needs
replacement, refer to
Maintenance/Service
on page 29.
