This unit
The Stanford Research QMS100 is a quadrupole mass spectrometer for residual gas analysis and vacuum diagnostics. It detects and quantifies gas species and contaminants within vacuum systems across a mass range of 1 to 100 amu. Built on a two-stage pressure-reducing inlet system, the QMS100 samples gases at atmospheric pressures (10 mbar to 1 bar) and conditions them for analysis by a high-vacuum quadrupole mass analyzer.
A capillary inlet reduces pressure by three decades, followed by a hybrid turbomolecular/drag pump stage that achieves approximately 10⁻⁶ Torr analysis conditions. Solenoid valves govern gas flow throughout the system.

Stanford Research QMS100 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Stanford Research QMS100. Calibration covers calibration scope varies by instrument type: vacuum gauges are verified at multiple pressure points against NIST-traceable pressure standards; spectrophotometers at wavelength accuracy and photometric accuracy points; strain gauge indicators at bridge excitation accuracy and full-scale output accuracy; pH meters against certified buffer solutions at pH 4, 7, and 10.. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Stanford Research QMS100 faults: vacuum gauge filament failure (ionization gauges), spectrophotometer D2 lamp end-of-life, wavelength motor failure, strain indicator front-panel binding post corrosion, pH electrode conditioning failure. Most specialty laboratory instruments fail at their electromechanical interfaces first — vacuum gauge connectors and filament assemblies, spectrophotometer lamp housings and motor drives, strain indicator binding post corrosion. Component-level repair is standard; manufacturer support for legacy instruments is often limited, making third-party bench repair the practical path.

Stanford Research QMS100 calibration cost
NIST-traceable calibration for the Stanford Research QMS100 is $450 (standard — pass/fail certificate and calibration sticker) or $650 (full measured data at every test point, reference standards documented, traceability chain included). Calibration for this instrument covers calibration scope varies by instrument type: vacuum gauges are verified at multiple pressure points against NIST-traceable pressure standards; spectrophotometers at wavelength accuracy and photometric accuracy points; strain gauge indicators at bridge excitation accuracy and full-scale output accuracy; pH meters against certified buffer solutions at pH 4, 7, and 10.. Turnaround is 1 to 3 business days after receipt. See full calibration details →
