Optimize Gas Analysis with our Fixed Magnetic Sector Spectrometers

Our real-time MGA™ fixed magnetic sector spectrometers are engineered to meet and exceed gas analysis needs across a wide range of industries including life sciences, iron and steel, ammonia production, ethylene oxide, and ethylene cracking. Designed for precision and speed, these advanced mass spectrometer gas analyzers offer a broad dynamic range, from high parts per million (ppm) up to 100%, for accurate, speciated gas composition in real time.

Thanks to a fixed magnet design, the MGA™ delivers fast, accurate, and stable analysis of up to 16 gas components in less than one second. For added flexibility, the optional multi-stream sampler supports up to 100 streams with rapid purging and selection. Combined with parallel spectrum processing, this setup enables complete stream analysis every 3 to 10 seconds, making it one of the fastest process gas analyzers available today.

In fermentation processes, the MGA 1200CS plays a critical role in bioreactor off-gas analysis. It offers real-time data for OUR/CER/RQ calculations, enabling immediate process adjustments and eliminating the delay of lab sample testing. This helps maximize product yields, ensure complete clean-in-place (CIP) verification, and maintain strict quality standards. Its low drift performance ensures long-term stability, enhancing the accuracy of every measurement.

Moreover, our fixed magnetic mass spectrometer is ideal for R&D and small-scale fermentation, now featuring a low-flow capability that supports bioreactors as small as 250 mL. This is especially valuable in pharmaceutical fermentation, industrial biotech, and mammalian cell culture applications. In particular, it provides high-precision oxygen analysis even at sparge gas flow rates as low as 20 cc/min—critical for sensitive cell culture environments.
