Agilent Technologies 5975 manual Instrument Identification, MSD versions

General Information

Instrument Identification

Each 5975 Series Mass Selective Detector (MSD) is identified by a unique 10-character serial number. This serial number is located on a label on the lower left side near the front of the instrument. On CI upgrades, a second serial number is located on the flow module.

When corresponding with Agilent Technologies about your instrument, be sure to include the model number and both full 10-character serial numbers.
