Cabin Air Sensor Solutions (CASS) has developed a sensor able to detect in real-time, individual poisonous compounds that can be present in an aircraft cabin. Until now it has not been possible to detect these poisonous compounds to establish and prove their presence. 

 

Circad developed the PCB design for an initial bench device, and then integrated these embedded systems into a hand-held device, and developed the prototype electronics for collecting and presenting the data through custom designed software. 

 

The initial handheld unit design and detection capability has been witness tested and verified using Gas chromatography–mass spectrometry (GC MS) by the National Physical Laboratory in Teddington, UK for the detection of low-level TBP in ‘real-time’.
