MMS 2000

1st Detect (formerly iONTRAC) introduces the MMS 2000 process analyzer which combines the selectivity, speed, and sensitivity of an ion trap mass spectrometer with ruggedized packaging, user-friendly software, and ease of operation. The versatile instruments can be customized to a wide variety of detection, analysis, and PAC/PAT applications directly on the plant floor. Streams and ambient environments can be monitored in real-time and time-trend analysis or alarm conditions reported over industry standard Ethernet RJ-45.


  • Measurement Method: Ion trap mass spectrometer
  • Mass Range: 45–400 amu (standard)
    Custom ranges over 15 amu to 500 amu available
  • Ionization Source: Internal EI (optional photoionization)
  • Sampling Method: Membrane inlet (optional preconcentrator or capillary)
  • Scans/Sec: 1 spectra/sec (typical) 7 spectra/sec (maximum),
    with 14 TIC points/sec. Faster scan rates require special settings.
  • Gases Monitored: User programmable
  • Mass Stability: Within ± 0.5 amu over an 8-hour period
    (measured at m/z = 91 amu xylene with continuous sampler)
  • Long Term Mass Accuracy: < 5 % RSD
    (measured at 91 amu xylene over 1 month)
  • Dimensions (W x H x D): 24″ x 30″ x 12″ (61 cm x 76 cm x 31 cm)
  • Sample Inlet: 1/2″ SwageLok (customizable for specific applications)
  • Sample Flow: (maximum) Capillary 100 μL/min, Heated Membrane 600 mL/min, Preconcentrator 1 L/min
  • Communication Protocol: IEEE 802.3 10/100 Ethernet
