Title
(EN) ANALYZER AND METHOD FOR TESTING A SAMPLE
(FR) ANALYSEUR ET PROCÉDÉ POUR TESTER UN ÉCHANTILLON
Abstract
(EN)
An analyzer for testing a biological sample is proposed, wherein the analyzer comprises a pressurized gas supply having an intermediate gas storage that is fluidically arranged between an intermediate valve and an actuation valve. A method for testing a biological sample is proposed, wherein the power supply of an intermediate valve is cut off when the valve starts to change its position and/or wherein the pressure of an intermediate gas storage located downstream of an intermediate valve is controlled. Further, a method for inspecting an analyzer, in particular its pressurized gas supply, is proposed, wherein the pressure drop in a main gas storage is measured and compared to a reference pressure drop in order to inspect the analyzer.
(FR)
L'invention concerne un analyseur pour tester un échantillon biologique, l'analyseur comprenant une alimentation en gaz sous pression ayant un réservoir de gaz intermédiaire qui est disposé de manière fluidique entre une soupape intermédiaire et une soupape d'actionnement. L'invention concerne un procédé pour tester un échantillon biologique, selon lequel l'alimentation en énergie d'une soupape intermédiaire est coupée lorsque la soupape commence à changer sa position et/ou la pression d'un accumulateur de gaz intermédiaire situé en aval d'une soupape intermédiaire est commandée. En outre, l'invention concerne un procédé pour inspecter un analyseur, en particulier de son alimentation en gaz sous pression, la chute de pression dans un réservoir de gaz principal étant mesurée et comparée à une chute de pression de référence afin d'inspecter l'analyseur.
