Agilent G3170-60775 is an internal analyzer assembly for the Agilent 5975C Series GC/MSD in an inert configuration with an ion source capable of operation up to 350 °C. The assembly forms a key part of the mass analyzer and is intended for service, repair, or refurbishment of Agilent 5975C GC/MSD systems.
The 5975C platform combines inert electron ionization (EI), a monolithic hyperbolic quadrupole mass filter, and Triple-Axis Detector technology for sensitive GC/MS analysis, including demanding and active compounds.
Inert EI Configuration
The 5975C Inert GC/MSD uses a noncoated inert EI source designed to reduce unwanted interactions between active analytes and ion-source surfaces.
Ion-source temperature range:
- 150–350 °C
The high-temperature source is particularly useful for:
- less volatile compounds,
- active analytes,
- pesticides,
- PAHs,
- environmental contaminants,
- complex matrices.
Quadrupole Analyzer
The 5975C platform uses a monolithic hyperbolic quadrupole mass filter.
Key platform specifications include:
- minimum mass: 1.6 u
- maximum mass: 1050 u
- resolution: unit mass, tune-adjustable
- mass-axis stability: better than 0.10 u over 48 h
- quadrupole temperature: 106–200 °C
Detection System
The 5975C uses a Triple-Axis Detector with long-life electron multiplier.
The Triple-Axis geometry helps reduce the direct impact of neutral species and photons on the detector, supporting low background and high sensitivity.
Electronic dynamic range: approximately 10⁶
Scan Performance
5975C electronics provide:
- scan rates up to 12,500 u/s
- write-to-disk rates up to 8,000 u/s
This supports fast GC separations as well as qualitative and quantitative GC/MS workflows.
Acquisition Modes
The standard EI configuration supports:
- Full Scan
- SIM – Selected Ion Monitoring
- combined Scan/SIM workflows depending on method and software
The platform supports up to 60 ions × 100 SIM groups.
5975C Temperature Specifications
- Ion source: 150–350 °C
- Quadrupole: 106–200 °C
- Transfer line: 100–350 °C
The 350 °C, Inert designation identifies the high-temperature inert analyzer/source configuration.
Compatibility
G3170-60775 is intended for:
- Agilent 5975C Series GC/MSD
- service of inert EI 5975C configurations
- matching 5975C analyzer hardware revisions
The 5975C platform was commonly paired with:
- Agilent 7890A GC
- Agilent 6890 GC
- Agilent 6850 GC
Exact analyzer compatibility depends on the hardware revision of the individual MSD.
