ASTG engineers gas analytical systems where measurement precision underpins safety, yield, and compliance. From semiconductor fabs to aerospace breathing-oxygen systems, from carbon capture pilots to industrial gas production, our instruments and integrated solutions are deployed wherever a wrong number has real consequences.

ASTG combines two complementary capabilities: a portfolio of productized analytical platforms designed and built in-house, and turnkey integration of best-in-class third-party analyzers into complete custom systems. Two flagship products anchor our portfolio. The FT2 is a next-generation FTIR multi-gas analyzer engineered for real-time monitoring across energy, semiconductor, and manufacturing environments. Built around the FT2, the AirBreather is ASTG's productized FTIR analytical platform. It was originally developed for CO₂ purity monitoring in the beverage industry, where it remains the workhorse for producers and the industrial gas majors that supply them, and it is now deployed across hydrogen purity, CCUS, and aviator breathing oxygen applications. Around these products, we design and deliver sample management systems, gas purity monitoring systems, calibration carts, and complete analytical packages built to customer specification.

In practice, that means oxygen analysis for defense and aviation, hydrogen purity monitoring for clean-energy carriers, CCUS instrumentation for capture pilots, and ultra-high purity monitoring for semiconductor fabs. Our customers include leading semiconductor manufacturers, industrial gas majors, beverage producers, government agencies, and the engineering firms that build our systems into theirs. Wherever measurement integrity matters, ASTG is engineered to be there.

Founded in 2001 and based in Newton, New Jersey, ASTG is independent and privately held, with a team of scientists, engineers, technicians, and field service specialists. Visit www.astg.com for products, applications, and case studies.
