摘要:
This invention relates a chemiluminescent gas analyzer for determining a concentration of a gaseous component (G1) in a sample gas mixture (2). The analyzer comprises a measuring chamber (3), an ozonizer (4) with ozone generating means (44) for producing ozone-containing gas (G2), input conduits (24, 23) for delivering the ozone-containing gas and said gas mixture into the chamber and an outlet (18). A detector (7) receives radiation (E) emitted as a consequence of a reaction between the gaseous component and the ozone-containing gas. Said analyzer further comprises a flow delay device (41) in or upstream the input conduit for said ozone-containing gas and downstream from the ozone generating means (44) of the ozonizer. The flow delay device has a delay volume (VD) causing a predetermined delay time (T) for the flow of the ozone-containing gas from said ozonizer to said measuring chamber (3).
摘要(中):
本发明涉及一种化学发光气体分析仪,用于测定样品气体混合物(2)中气态组分(G1)的浓度。 分析仪包括测量室(3),臭氧发生装置(44)的臭氧发生器(4),用于产生含臭氧气体(G2),用于输送含臭氧气体和所述气体混合物的输入管道(24,23) 进入腔室和出口(18)。 检测器(7)接收由于气体组分和含臭氧气体之间的反应而发射的辐射(E)。 所述分析器还包括在用于所述含臭氧的气体的输入管道中或上游的臭氧发生装置(44)的下游的流动延迟装置(41)。 所述流动延迟装置具有延迟体积(VD),其导致从所述臭氧发生器向所述测量室(3)流出含臭氧气体的预定延迟时间(T)。
