7. Using the autosampler controls open the valves for
any lines.
8. Gently pull the syringe plunger down and align it with
the drive bar.
9. Reinstall the shoulder screw.
NOTE: The shoulder screw should be able to be
installed finger tight until it is flush with the syringe
plunger. If the screw cannot be turned with only your
fingers, adjust the plunger and try again. Once the
screw is flush with the syringe plunger, it may be
tightened with a screwdriver.
Volume Calibration
Use DI-grade water at room temperature.
1. Weigh empty sample collection vials or test tubes and
record the results (tare weight). Caps are required in
order to ensure accuracy.
2. Program the autosampler to collect the required
sample volume.
3. Weigh full sample collection vials and subtract the
empty (tare) weight from the full weight. Make any
necessary calculations to account for water density.
