1ST Detect’s OEM CIT 1000TM is a mass spectrometer component that gives users the power of mass spectrometry in a small, easily customizable platform that can be integrated into customer-specific packaging and equipment, and is well-suited to be integrated with application-specific sampling or separation technology.

Variants of the OEM 1000 have been selected by our partners in development programs for the Department of Defense (DoD) and the Transportation Security Administration (TSA).

  • Can be tuned to provide broadband analysis over a wide range of masses, or can be optimized for a specific detection range.
  • Configurable to fit an array of platforms including benchtop platforms, rack-mount systems, or ruggedized field portable packages.
  • For GC application, vacuum system is compatible with air, hydrogen, nitrogen and helium carrier.
  • Can be offered with increased capacity vacuum systems to accommodate high flow inlets and systems (e.g., fast GC) up to 1.5 ml/min.
  • Operable with a range of background gases for specific applications (e.g., hydrogen carriers for gas chromatography).
  • For applications that do not require external pumping (e.g., semi-conductor process control), we can provide the advanced chemical detection capabilities without the integrated vacuum pumping system.
  • Mass spectrometric quality analysis can be added to existing instruments.
  • Lower cost alternative to analyzing samples using external instrumentation.
  • Versatile inlet configurations allow customized coupling to customer specific systems.
  • Mass spectrometer control software can be integrated with customer software presenting a unified customer interface.
  • Air can be used as carrier gas, no cylinders or external supply required.
  • Data analysis software package is easily configured to customer requirements.
  • Mass Range: 45–400 amu (standard)
    Custom ranges available 15–500 amu.
  • Resolution: Unit Mass
  • Scans/Sec: 1 spectra/sec (typical), 30 spectra/sec (maximum). Faster scan rates require special settings.
  • Sensitivity: Membrane Inlet 500 ppb, Preconcentrator 500 ppt using 30 sec sampling time. Measured at m/z = 91 amu xylene*.
  • Weight: 15 lbs (7 kg)
    Varies based on configuration.
  • Size: 7.5″ x 13″ x 7.5″ (19 cm x 33 cm x 19 cm)
    Varies based on configuration.
  • MS/MS Capable: No collisional gas or buffer gas required.
  • Input: 24 VDC
  • Power: Varies based on configuration.
  • Ionization Mode: Electron Ionization
