Toxic Industrial Chemical Sensing (TICS)
A toxic industrial chemical sensor (TICS). It's designed to sense common toxic industrial chemicals such as ammonia, chlorine, hydrochloric acid, acetic acid, hydrogen sulphide, and hydrogen fluoride, The chart below is showing their IR absorption bands, not considered particularly lethal, but can easily be acquired, concentrated, and planted in public food, water, and urban environments to pose a significant threat to the general public.
A sensor on a micro-chip using an array of the MFPTF cavities, each tuned to a specific wavelength to sense a specific chemical. It's capable of detecting of a wide range of chemicals simultaneously.
