Q:
“What if the instrument indicates low flow when the input
pressure is adequate?”
A:

Set instrument oven temperature to 80 °C or below.
•
Obtain several ounces of isopropyl alcohol (IPA).
•
Fill a sample bottle ½ to ¾ full with IPA; fit with a cap and septum.
•
Place an empty sample bottle at the outlet port at the back of the instrument to
catch expelled solvent.

From the MAIN TEST SCREEN, navigate MENU
DIAGNOSTIC
MENU
MANUAL FLOW CONTROL MENU, and switch the MANUAL
FLOW CONTROL to BOTTLE PURGE.
•
After 5-10 seconds, solvent should begin to be expelled from the outlet port at the
back of the instrument.
