Installation
This chapter contains instructions for installing the HP 5973 MSD system.
Installation of any MSD system includes the following steps:
• Inspection of shipped materials
• GC installation and preparation
• MSD installation
• Data system installation
• GC and MSD integration
• Performance evaluation
• Customer familiarization
Installing the CI MSD system requires additional steps:
• Methane/isobutane gas purifier installation
• Methane reagent gas line and gas purifier purge
• Methane reagent gas line hookup
After system performance has been verified in EI mode, the MSD must be
switched to CI mode and evaluated:
• CI ion source and CI interface tip seal installation
• Bakeout and purge at least 2 hours
• CI setup
• PCI autotune and sensitivity verification
• NCI autotune and sensitivity verification
The EI/CI interface on the CI MSD requires a different column installation
procedure.
The HP 59864B vacuum gauge controller is required for CI operation.
