Chemical Detection Device
Optical spectroscopy, is a very powerful technic for toxic gas analysis. It enables measurements of light ab-sorption, emission, scattering and rotation, significant structural data and chemical definition of these. Each element of an optical filter series transmits the filtered light to the matching element of a photodetector series. It uses a Fourier transform infrared microscope (FTIR) to record the optical power transmitted from each filter.

The acquired data is transmitted to an RLS-based algorithm that estimates the incident spectrum by using the transfer spectra of the filter and dynamically reconfigures both the filter transfer spectrum and the infrared light source spectrum of the FTIR system. A dedicated spectral-matching algorithm compares the measured spectra with those stored in the system library, which includes common chemical warfare agents (CWAs) and toxic industrial chemicals (TICs).
The Toxic Industrial Chemicals (TICs) detector is designed to automatically monitor and generate alarms for substances such as NH₃, AsH₃, CS₂, HCN, HNO₃, HCN₂, PCl₃, and SO₂. An alert is issued whenever the concentration of any monitored substance exceeds predefined safety threshold levels.
The Chemical Warfare Agents (CWA) detector provides automatic monitoring of nerve agents (GA, GB, GD, GF, VX) and blister agents (HD and L). The system immediately warns the user if the detected concentration of any chemical warfare agent surpasses the configured threshold values.
In addition, the chemical detection system issues warnings for VOCs, VVOCs, LEL conditions, oxygen levels, sulfur dioxide, and phosphate gases, ensuring comprehensive situational awareness and enhanced protection against chemical hazards.
