Title (EN) INSTRUMENT FOR CHEMI-OR BIOLUMINESCENT ANALYSIS
(FR) INSTRUMENT POUR ANALYSE CHIMIO- OU BIOLUMINESCENTE
Abstract:
(EN) An instrument for chemi- or bioluminescent analysis of the concentration of a constituent of a sample gas (G1) which in a reaction chamber (C) reacts with a liquid reagent (R1) in a luminescent manner. The liquid reagent (R1) is ejected into the reaction chamber (C) by ejection means. The sample gas (G1) can be used as propellant in the ejection means (E) sucking the liquid reagent (R1) into the propellant and as an aerosol be sprayed into the reaction chamber. Carefully mixed with the sample gas, it generates chemiluminescent radiation (L1, L2) in the field of view of a photodetector (D). The propellant (G1) can also be prepared so that either heating or cooling occurs on expansion in the reaction chamber (C). By providing walls of the reaction chamber with reflecting layers, the main portion of the luminescent radiation reaches the detector (D).
(FR) Instrument d"analyse chimio- ou bioluminescente de la concentration d"un composant d"un gaz echantillon (G1 qui, dans une chambre de reaction (C) reagit avec un agent de reaction ou reactif liquide (R1) de maniere luminescente. Le reactif liquide (R1 est ejecte dans la chambre de reaction (C) a l"aide de moyens d"ejection. Le gaz echantillon (G1 peut etre utilise comme propulseur dans des moyens d"ejection (E) par aspiration du reactif liquide (R1) dans le fluide de propulsion et, comme un aerosol, peut etre vaporise dans la chambre de reaction. Soigneusement melange avec le gaz echantillon, il produit une radiation chimioluminescente (L1, L2) dans le champ de vision d"un photo-detecteur (D). Le fluide de propulsion (G1 peut aussi etre prepare de sorte qu"il se produise un rechauffement ou un refroidissement lors de la detente dans la chambre de reaction (C). En garnissant les parois de la chambre de reaction avec des couches reflechissantes, la partie principale de la radiation luminescente atteint le detecteur (D).
