Not just fast. It's FREAKY FAST!

Introducing the all-new MATE MGA 1100i™, the fastest multi-component gas analyzer for on-line and real-time analysis.

Incorporating industry-proven magnetic sector mass spectrometry, the MATE MGA 1100i leverages a unique fixed Faraday collector architecture that provides unmatched responsiveness and stability. Individual Faraday collectors coupled with the latest in ultrafast, dual-gain electrometer technology delivers analysis of four life gases as fast as 0.1 seconds!

Magnetic sector technology has been leveraged for some of the most cutting edge, demanding applications that require no compromise and are mission critical. Applications including life gas monitoring in space, ambient air monitoring for extended submersion of submarine fleets, military altitude testing and diver pressure training have relied upon the robustness of these systems.

Key features include:

✔️ Four life gases (N2, O2, CO2, Ar) standard with ability to add up to eight optional additional gas


✔️ Response time for a single 4-gas measurement is 0.15 seconds.

✔️ Stability of measurement is second to none...calibration typically at 6-month intervals

✔️ Up to 16 streams can be multiplexed

✔️ Small physical footprint < 2.5 ft² (0.23 m²)

✔️ Intuitive, easy-to-use LabVIEW™ based MATE software requires no analyzer or mass spectrometer


✔️ Where permitted, analyzer can be fully monitored remotely for predictive maintenance

✔️ Industry standard digital and analog output protocols

✔️ Value driven when compared to other process mass specs

A signature feature of the MATE MGA 1100i is the speed of analysis of the base four life gases - N2, O2, CO2, & Ar. This technology has been so successful that it has been adopted by military labs and pulmonary research institutes where respiration rates exceeding 60 breaths/minute can be discretely analyzed and transmitted in real-time.

  • T10 - T90 response time in < 150 milliseconds

  • Sampling frequency can be reduced if required

  • Sample transport time varies depending on number of streams and transport distance; at analyzer inlet transport time < 300 milliseconds

Software.  Based on the National Instruments LabVIEW™ platform, MATE keeps it simple, so you can focus on your system’s performance and uptime, rather than worrying about learning another complex spectroscopy software environment. We realize you simply want the data and will manipulate it in your own control systems and environments. That’s why we simplify it.

Interface Solutions

MATE understands that in order for an on-line analyzer to produce reliable results, it must be properly interfaced to the process streams as well as the control system. MATE, along with our partners can deliver the interfaces that your application demands.

About MA Tech Services, Inc...Our Story

It began with SERVICE. Launched in 1989, MA Tech Services, Inc. (or known more formally around the circles as MATE) created an independent mass spec service organization. We quickly earned a reputation for our ability to fix problems. In 2004, MATE evolved with acquisition of the legendary MGA 1100 product line from GE Medical Systems (who had previously acquired it from Perkin-Elmer). We developed a digital interface to breathe life into the MGA installed base. Now, we have leveraged those experiences to create our next evolution, the MATE MGA 1100i.
