The object of Halothane Meter (HM) study is to estimate its reliability (accuracy and stability) and its possible effect on the degradation of the molecule by the action of the UV (254 nm). The zero instability of the apparatus, clinically evident, is due to the constructor who undertakes to modify it. The molecule analysis, treated in vivo (4 hours of anesthesia) and in vitro by irradiation respectively by the HM (cathodeon 254 nm) and a source of some wavelength UV is realised by UV spectrophotometry, IR spectrophotometry, RMN spectrometry. The results of all analysis allow to exclude the molecule degradation which could impede the recirculation of treated gas in a closed circle.
氟烷测量仪（HM）研究的目的是评估其可靠性（准确性和稳定性）以及紫外线（254纳米）作用对该分子降解可能产生的影响。该仪器临床上明显的零点不稳定性是由负责进行修改的制造商造成的。通过紫外线分光光度法、红外分光光度法、核磁共振光谱法分别对在体内（麻醉4小时）以及体外经HM（254纳米阴极射线）和某一波长紫外线源照射处理后的分子进行分析。所有分析结果均排除了可能阻碍处理后的气体在封闭回路中再循环的分子降解情况。
