Letter from our CEO

Advanced Analysis / Real-Time Results / Precision FTIR

Product Launch: FT2-FTIR

Introducing the next-generation FTIR gas analyzer for continuous,real-time, multi-gas monitoring. Combining high-resolution FTIR spectroscopy with a TE-cooled MCT detector, the FT2 delivers sub-ppm accuracy, fast response, and 24/7 reliability in the most demanding environments. Built for process control, emissions monitoring, and gas purity analysis, the FT2 sets a new benchmark in performance and precision.

Designed for gas purity verification, environmental monitoring, and advanced analytical applications, ASTG's products deliver reliable performance across critical industries.

Gas Purity Verification: AirBreather Systems™
AirBreather Systems™ verify gas purity on site. They were developed over five years, including field trials and in-service validation, and are designed to be economical to run and simple to maintain.
Ultra High Purity Monitoring
ASTG's Ultra High Purity (UHP) gas monitoring systems measure trace impurities in the gases used in semiconductor manufacturing and medical processes. They run on ASTG's own software.
Atmospheric Monitoring Cart (AMC)
The Atmospheric Monitoring Cart (AMC) is a mobile system for real-time air quality monitoring. It detects trace amounts of toxic compounds in production facilities.
Laboratory Services
ASTG's laboratory provides analytical testing, from environmental monitoring to materials analysis.
Semiconductor Business Expansion
ASTG supplies gas purity monitoring systems to semiconductor fabs.
