Abstract: We propose a new detection method based on cataluminescence (CTL) to detect isoflurane vapor, a typical anesthetic agent, continuously. The CTL of isoflurane vapor is observed during catalytic oxidation of isoflurane by the catalyst of γ-Al2O3 activated with Tb3+. This is the first observation of the CTL of the isoflurane vapor. The reproducible CTL response is observed at 600°C of catalyst temperature. The CTL intensity of isoflurane is proportional to the square root of the flow velocity ranging from 10.6 to 53.1cm/s. This result directly shows that the rate of catalytic reaction emitting CTL is under the diffusion controlled conditions at 600°C. The CTL intensity of isoflurane is nearly proportional to the isoflurane concentration ranging from 10 to 50ppm. [Copyright &y& Elsevier] |
