Abstract

In order to solve problem that the traditional gas detector are unable to detect Volatile Organic Compounds(VOC), the photo-ionization gas detector that can detect the VOC effectively by using the photo-ionization have been designed. The principle, structure, technology for ultraviolet (UV) light and ionization chamber and small-signal processing of the photo-ionization gas detector are introduced. Especially the detector incorporates an innovating ionization chamber, which can effectively improve the ionization efficiency and sensitivity. The instrument can effectively detect total hydrocarbon gas, has the advantages of small volume, stable working state of high sensitivity and the smallest error.
