摘要：a gas flow cell for spectrophotometric analysis of chemical
compounds.consisting of a preferably cylindrical, elongate body (1) provided with acentral channel (2) is restricted to its longitudinal ends (3, mutually parallel windows(4)are sealed with a channel (2) and are transparent to the radiation used for theanalysis.the channel (2) is in communication at one end with connections (7).(8) for thecarrier gas and the injection of the compound and has at the other end an outlet (10) forcompounds and the carrier gas.the invention is characterized by the fact that, at the sametime, the channel (2) and at a distance from it is a second channel (11) for separation andconnected between the connections (7)8) and the end of the first channel (2). in thechannel (11) is a tubular column (12) filled with a replaceable chemical composition.
