MGA 1200EC 

MGA 1200EC Mass Spectrometer Gas Analyzer

Our Extrel MGA™ 1200EC™ Process Mass Spectrometer Gas Analyzer is a fixed magnetic sector analyzer that provides rapid, accurate and stable real-time analysis of up to 16 gas components in multiple gas streams. It’s fast!  With hardware configurable to provide both continuous and instantaneous readings of gas concentrations with less than 1 second response time for all components, it can provide mid-ppm to 100% level analysis of components. 

The MGA 1200EC delivers continuous and instantaneous analysis with an unmatched stability providing best-in industry drift specification, the longest intervals for calibration along with the ability to interface to process streams of driving both rotary and solenoid manifolds.  Available for general purpose and hazardous area operation.

  • Windows® based Prime™ software allows operator access and control of a variety of operating parameters
  • Provides ppm to % level analysis of components
  • Long-life turbo molecular pumping system allows rapid vacuum pump down in less than 2 minutes
  • Best-in-industry drift specification and longest intervals for calibration.
  • Optional validation assistance program for 21 CFR Part 11 compliance.
  • Analyze up to 128 streams, including both process and calibration gases, in user-defined order
  • Standard communications:  RS-232 Serial, Modbus® RTU & TCP/IP
  • Optional communications:  Analog (0-10 Vdc, 4-20 mA), OPC®, Profibus
  • Scalable sampling systems and calibration manifolds available


Prime™ Software is used by the MGA 1200EC Process Mass Spectrometer Gas Analyzer for process monitoring of multi-component gas streams. A Windows® based graphical interface provides the user with capabilities such as real-time analysis, automatic calibration, trending, sample system control and DCS communications. The Prime software is delivered with a data station.

  • Delivers real-time displays:  calibration, trending, and sample system control
  • Formats include gauge, tabular or multi-stream trending. Up to 96 user-defined elements can be displayed in real- time on six pages.
    • MGA electrometer outputs
    • MGA compositional analysis
    • User-defined calculations and alarms
    • User-supplied analog and digital inputs


  • Improved reliability
  • Low cost of ownership 
  • Meet compliance requirements
  • Backed by global service and support
