Abstract :
Describes experimental results of a novel intrinsic gas sensor, based on plastic optical fiber (POF), to detect and to measure relative concentration of nitrous oxide in oxygen in anesthetic mixtures. The sensor was able to measure concentrations from zero to 100 V%, in a total flow of 10 l/min, with sensitivity around -2.32 10-3 dB/V%.
