Abstract: Arrangement for trace gas analysis with a radiation source for UV light and with an ionisation chamber and an anode and a cathode assigned to the latter. In the case of such an arrangement, it is intended to improve the measuring accuracy and sensitivity. According to the invention, this is achieved by locating the ionisation chamber inside a space bounded by at least one anode (4.1; 4.2; 4.3) and at least one cathode (5.2; 6.2). In particular, an elongated anode (4.1; 4.2; 4.3) is arranged, to which an elongated cathode (5.2; 6.2) is assigned such that the ionisation chamber is formed as a flow channel (7.2; 8.2) between the two and such that the flow channel is covered on both sides of the anode and cathode vertically with respect to its extent between the anode and the cathode. The arrangement is suitable in particular for detecting pollutants.
