VOC Sensors: Volatile Organic Compounds Sensor

The most commonly used method for detection of VOCs is a photoionization detector. VOC molecules are complex and easily broken down by high energy photons. VOC sensors use a bright ultraviolet light source to knock electrons out of the VOC molecule; the electrons are measured and their flow indies that VOC molecules are present at the sensor.
