Chemical Detection Device

The Chemical Detection Device is developed to detect and identify chemical warfare agents and toxic industrial chemicals by analyzing their infrared spectral signatures. By continuously monitoring ambient air, the system provides early warning when hazardous chemical concentrations exceed predefined safety thresholds.

The device is deployed in military vehicles, shelters, command centers, border security points, and critical infrastructure areas where chemical threat monitoring is required. It is suitable for both fixed and mobile CBRN detection applications supporting operational safety and situational awareness.

The system operates using optical spectroscopy combined with a Fourier Transform Infrared (FTIR) measurement approach. Filtered infrared light is transmitted through an optical filter array to corresponding photodetectors, where the transmitted optical power is recorded.

Measured data is processed by an RLS-based algorithm that estimates the incident spectrum using known filter transfer spectra. The algorithm dynamically reconfigures both the filter transfer characteristics and the infrared light source spectrum of the FTIR system. A dedicated spectral matching algorithm then compares the measured spectrum with reference spectra stored in the system library.

The internal library includes chemical warfare agents and toxic industrial chemicals, enabling rapid and accurate identification.

The Toxic Industrial Chemicals detector automatically monitors substances including ammonia, arsine, carbon disulfide, hydrogen cyanide, nitric acid, cyanogen compounds, phosphorus trichloride, and sulfur dioxide. An alarm is generated when concentration levels exceed configured limits.

The Chemical Warfare Agents detector provides automatic monitoring of nerve agents (GA, GB, GD, GF, VX) and blister agents (HD and L). Immediate warnings are issued when detected concentrations surpass defined threshold values.

In addition, the system provides alerts for volatile and very volatile organic compounds, lower explosive limit conditions, oxygen concentration levels, sulfur dioxide, and phosphate gases.

The Chemical Detection Device continuously analyzes ambient air and identifies hazardous chemical substances through spectral comparison and concentration evaluation. By providing real-time detection, classification, and alarm generation for a wide range of chemical agents, the system supports early warning, threat assessment, and protective response in chemical hazard environments.
