Model FT2
The ASTG FT2 is a high-performance, fully automated FTIR gas analyzer designed for continuous, real-time monitoring of multiple gas species in industrial and environmental applications. Based on Fourier Transform Infrared (FTIR) spectroscopy, the FT2 transmits broadband infrared light through a temperature-controlled, multi-pass gas cell where target gases absorb specific wavelengths corresponding to their molecular vibrational modes. A Rock-solid Michelson-type interferometer modulates the IR signal, and the resulting interferogram is converted into a high-resolution absorption spectrum using a Fourier Transform. Advanced Partial Least Squares (PLS) chemometric algorithms allow for accurate quantification of gas concentrations, even in complex or overlapping spectral environments. A thermoelectrically (TE) cooled mercury cadmium telluride (MCT) detector ensures high sensitivity and low noise, enabling sub-ppm detection limits and fast response times. With a spectral range of 4,300 - 750 cm-1 and resolution down to 0.8 cm-1, the ASTG FT2 can simultaneously measure gases such as CO, C02, NOX, S02, NH3, CH4, HCl, and various VOCs. The system is easy to use, with an intuitive user interface and remote access capabilities. The FT2 is built for 24/7 unattended operation in demanding industrial environments, making it ideal for process control, CEMS, and regulatory compliance monitoring.
