Abstract

APPAREIL POUR L'ANALYSE DE SUBSTANCES EN COURANT GAZEUX DU TYPE A CAPTURE D'ELECTRONS, DU TYPE DETECTANT LA VARIATION DE FLUX D'ELECTRONS ENTRE DEUX ELECTRODES AU PASSAGE D'UNE SUBSTANCE ABSORBANT LES ELECTRONS DANS UN COURANT GAZEUX, L'UNE DESDITES ELECTRODES ETANT CONSTITUEE PAR UNE CHAMBRE DONT LES PAROIS SUPPORTENT UNE SOURCE RADIOACTIVE, TANDIS QUE L'AUTRE ELECTRODE COLLECTE LE COURANT DE GAZ QUI A TRAVERSE LA CHAMBRE D'IONISATION, CARACTERISE EN CE QUE LA SECONDE ELECTRODE 18 EST LOGEE DANS UN SIEGE DONNANT SUR LA CHAMBRE QUI FORME LA PREMIERE ELECTRODE 16 ET EST ACCESSIBLE DU COTE OPPOSE A LA CHAMBRE POUR UN DEMONTAGE RAPIDE SANS INTERVENTION SUR LA CHAMBRE RADIOACTIVE. APPLICATION AU DEMONTAGE D'ELECTRODES SANS RISQUE DE CONTAMINATION RADIOACTIVE.APPARATUS FOR THE ANALYSIS OF SUBSTANCES IN A GAS CURRENT OF THE ELECTRON CAPTURE TYPE, OF THE TYPE DETECTING THE VARIATION OF ELECTRON FLOWS BETWEEN TWO ELECTRODES ON THE PASSAGE OF A SUBSTANCE ABSORBING ELECTRONS IN A GAS CURRENT, ONE OF THE SAID ELECTRODES BEING CONSTITUTED BY A CHAMBER WHOSE WALLS SUPPORT A RADIOACTIVE SOURCE, WHILE THE OTHER ELECTRODE COLLECTS THE GAS CURRENT THROUGH THE IONIZATION CHAMBER, CHARACTERIZED IN THAT THE SECOND ELECTRODE 18 IS HOUSED IN A SEAT OVERLOOKING THE CHAMBER FORMING THE FIRST ELECTRODE 16 AND IS ACCESSIBLE FROM THE OPPOSITE SIDE TO THE CHAMBER FOR QUICK DISASSEMBLY WITHOUT INTERVENTION ON THE RADIOACTIVE CHAMBER. APPLICATION TO ELECTRODES DISASSEMBLY WITHOUT RISK OF RADIOACTIVE CONTAMINATION.
