RELATIVELY FREE OF AIR AND/OR MOISTURE
BEFORE APPLYING THE IONIZING VOLTAGE.
KEEP THE SERIES 1200 POWER OFF UNTIL THE
ANALYZER IS FULLY PURGED.
Note: Air leaking into the sampling system will cause erratic or

into the system for only a few minutes, you must purge the
regulator and the system for at least 1 hour before the
readings stabilize. See Section 3.6.
