Trace Nitrogen in Argon Analyzer
CAUTION:
IT IS THE RESPONSIBILITY OF THE END USER TO
PROVIDE A SUITABLE SAMPLE SYSTEM CAPABLE OF
DELIVERING CLEAN, PARTICULATE-FREE ARGON
THAT IS AIR AND MOISTURE FREE.
EQUIPMENT DAMAGE MAY RESULT IF THE
ANALYTICAL CELL IN THIS UNIT IS EXPOSED TO
PRESSURE, CAUSING IT TO BREAK OR SHATTER.
TO PREVENT THIS, NEVER EXCEED 20 PSIG (138
KPA) ON THE INPUT PORT AND ALWAYS MAINTAIN
THE VENT AT ATMOSPHERIC PRESSURE.
DO NOT BLOCK THE VENT.
The external sample system should be capable of supplying clean,
particulate-free and moisture-free sample gas that is also free of air and
moisture. If air or moisture is ionized in the analytical cell, ozone
emissions are possible. These same conditions apply to any calibration
gases used.
Section 3.6.1 provides more information on a suitable sample
system.
If air enters the sample system, it can be removed by purging the
sample lines. Recalibration is not necessary.
