HP 5971 MSD Mass Selective Detector, Agilent Technologies/HP (CAT#: STEM-MSPO-0156-ZJF)

The manufacturer of the HP 5971 MSD Mass Selective Detector, Agilent Technologies/HP is Agilent Technologies/HP.
Refurbished Hewlett Packard/HP 5971 Series Mass Selective Detector (HP 5971A) with diffusion pump, transfer line, E2M2 Edwards pump, vacuum hose and connections, clamps and O-rings. Available with 5890 Series II or individually.

Condition: Refurbished, Certified Pre-owned
Dynamic range: A logarithmic preamplifier provides more than six decades of dynamic range.
Ionization energy: 70 eV from either filament
Mass range: 1.2 – 650 amu
Mass resolution: 0.5 +/- 0.05 amu throughout the mass range
Scan speed: Eight user-selected scan rates with a maximum of 2000 amu/sec with 0.1 amu mass resolution.
SIM mode: In the selected ion monitoring (SIM) mode, the MSD monitors up to 20 individually selected masses at one time. Up to 200 groups of 20 masses can be selected from each run. Dwell time for each mass is user-selectable from 10 msec to 32767 msec.
Temperature Control: The GC/MSD interface temperature is user-settable from 250°C to 320°C. The end of the GC/MSD interface conductively heats the ion source and mass filter. The vacuum manifold is not otherwise heated.
Total ion mode: AC voltage-only mode, with adjustable low-mass cut-off, allows the HP 5971A to operate as a non-specific, high-sensitivity detector.
Vacuum system: Vacuum is maintained by a vapor diffusion pump backed by a two-stage, direct-drive mechanical pump. Overall system pumping speed is approximately 60 liters/sec for helium. The vacuum system can accommodate capillary flow rates up to 1ml/minute ( atmosphere ) of helium.
