METHOD AND DEVICE FOR IONIZING CHEMICAL SPECIES, AND DETECTOR FOR IDENTIFYING IONIZED SPECIES

摘要

The invention relates to a photo-ionization detector and its source of ultraviolet radiation. This detector comprises: INDUCER 8, CONCENTRIC A 2; A FLAT CHAMBER 25 OR ULTRAVIOLET RAYS, PRODUCED IN 2, PENETRATING BY A TRANSPARENT WINDOW 4; ELECTRODES, CONNECTED BY CONDUCTORS 53, 56 TO A HIGH CONTINUOUS VOLTAGE SOURCE 52, AND TO AN APPROPRIATE ION DETECTION CIRCUIT, FORMED IN THE CHEMICAL SPECIES TO BE DETECTED, THAT A CARRIER GAS DRAWED THROUGH THE CHAMBER 25. THE INVENTION IS APPLICABLE TO THE DETECTION OF IONIZABLE CHEMICAL SPECIES. / P
