Abstrakt: Abstract: We propose a new sevoflurane sensor utilizing cataluminescence (CTL) of catalyst activated with Tb3+ Sevoflurane is a typical anesthetic agent used on patients during their surgery. The CTL is a kind of chemiluminescence emitted during the catalytic oxidation of combustible gas. The reproducible CTL is observed during the catalytic oxidation of sevoflurane vapor in the air for catalyst at 600 °C. The CTL intensity is proportional to the square root of the flow velocity of air containing sevoflurane vapor ranging in flow velocity from 8 to 26.5 cm/s at 600 °C in catalyst temperature. The CTL intensity is nearly proportional to the sevoflurane concentration in the range of about 5 to 20 ppm. [ABSTRACT FROM AUTHOR]
