Programming
Only three modes contain programmable parameters:
•
SYSTEM SETTINGS mode to “set” system parameters.
•
RUN PARAMETER mode for regular programming of
sample processing.
•
COOLING CONTROL mode to program the tray cooling, if
installed.
System Settings
With the ProStar 400 in READY status, key in F,9 to select
SYSTEM SETTINGS mode. Press PROG/END to enable
programming of the following parameters (use STEP key to go to
the next parameter):
LOOP VOLUME
Enter volume of the installed loop: 0-999 µL. If using dispenser
controlled loopfill, this will set the loop overfill volume to 3X
loopvolume if loop <100 µL and 2X loopvolume for loops
>100 µL.
SAMPLE VOLUME
(STD/LSV)
Enter 0 to select STANDARD sample tray. Enter 1 if the optional
Large Sample Volume tray has been installed (48 vials of 5 mL
each).
FLUSH (VOL/TIME)
Enter 0 to select dispenser controlled loopfilling on a volume
basis. Enter 1 to select loop filling by sample headspace
pressure on a time basis. Filling on a time basis may be used for
large injection volumes (>500 µL) to shorten loopfill time.
For loopfilling on a time basis, mount the special drain
included in the Accessory Kit to allow for pressure
controlled sample transport and to prevent hydrostatic
sample flow which may empty your sample vial during
analysis time.
