Abstract
The retention of N2O in samples of N2O in operating theater air held in disposable plastic syringes, glass syringes and custom-made nylon film bags was studied by gas chromatography at intervals of 90 min, 24, 48 and 120 h after filling the containers. After 24 h the nylon bags retained a mean concentration of 94.5% of the original concentration of N2O. The disposable plastic syringes and glass syringes were unsatisfactory and retained only 80% of the original concentration of N2O after 90 min. These values decreased to 51% and 31% of the original concentration of N2O, respectively, at 24 and 48 h.This publication has 0 references indexed in Scilit:
