To Replace The Methane/Isobutane Gas Purifier - HP 5973 MSD Hardware Manual

To replace the methane/isobutane gas purifier

Materials needed:
Methane/isobutane gas purifier (G1999-80410)
Front ferrule for 1/8-inch tubing (5180-4110)
Rear ferrule for 1/8-inch tubing (5180-4116)
Tubing cutter (8710-1709)
The methane/isobutane gas purifier needs to be replaced after four tanks of reagent
gas. This frequency may vary depending on purity of the gas and care taken in
uncapping and installing the gas purifier. A large leak upstream from the gas purifier
can quickly exhaust the reduced metal of its oxygen and moisture traps.
1 To install the methane/isobutane gas purifier, follow the instructions on
the label for installation and replacement intervals.
C A U T I O N Be sure not to remove the caps until you are ready to install the gas purifier. Only remove
the caps in the gas flow to prevent contamination by air.
