Method and device for ionizing the chemical species, and sensor in order to identify the species ionized

摘要

The invention relates to a sensor a photo - ionization and its source of ultraviolet rays. / p & & p & this sensor comprises: a tube discharge in the atmosphere gas 2 which is excited by a current of frequency radioelectric, passing through an inductor 8, which is concentric to 2; a flat chamber 25 or ultraviolet rays, products in 2, penetrate by a transparent ed ris tho 4; the electrodes, connected by conductors 53, 56 has a dc voltage source high 52, and has a circuit suitable for the detection of the ions, shapes in the chemical species we shall now describe, as a carrier gas drives through the chamber 25. / p & & p & the invention is applicable to the detection of chemical species which may be ionized.
