be a gas. In respect to the environment of people (normal conditions) any substance having a boiling point below 20 °C at normal pressure is a gas. The most light-weight gas is hydrogen (H 2, 14-times lighter than air), the heaviest gas is tungsten hexafluoride (WF 6, approx. ten-times heavier than air). Under normal conditions 1 cm3 gas contains about 30·1018 molecules, the average distance ...

Gas detector - Wikipedia

Semiconductor sensors, also known as metal-oxide-semiconductor sensors (MOS sensors), detect gases by a chemical reaction that takes place when the gas comes in direct contact with the sensor. Tin dioxide is the most common material used in semiconductor sensors, [9] and the electrical resistance in the sensor is decreased when it comes in contact with the monitored gas.

ionized gas is electrically charged and produces an electric current. The ion current is collected by the sensor, ampli˛ed and converted to a reading either in ppb or µg/m³. The greater the concentration of VOC’s in the air sample, the greater the current that will be generated and detected by the PID sensor. Using Krypton ( eV) Lamp to Optimize the PID Sensor A VOC will be ionized ...
