VOC sensor using high sensitivity electrodeless UV lamp

摘要

So far, the development of contact combustion sensor or electrode discharge lamps , radio frequency stimulate axial lamp and sensor VOC or toxic gas measurement sensitivity is decreased or the reaction speed required a large amount of gas , as well as slow . The present invention is a low density , such as VOC or toxic gases by measuring the electrical characteristic value change due to the action of the ionized particles after UV VOC or toxic gases to be measured by photoionization created by the magnetic pole of the low-frequency radio-frequency magnetic field 10,000 ppm (parts per million) can be measured from even the ppb (parts per billion).
