Performance of the Datex CD-101 and Godart Capnograph Mark II infra-red carbon dioxide analysers was investigated. The Datex machine uses a solid-state infra-red detector, while the Godart instrument uses a Luft detector. Both instruments were easy to use and the small size and light weight of the Datex was an added convenience. Linearity, stability, response time and the effect of nitrous oxide were within specification in both machines except when 10% carbon dioxide was used with the Datex analyser. Linearity of the Godart instrument was considerably better than 1% full scale deflection (fsd) quoted in the specification, while the Datex analyser was within 2% fsd (4% fsd with 10% carbon dioxide).
对Datex CD - 101和Godart二氧化碳分析仪Mark II型红外二氧化碳分析仪的性能进行了研究。Datex机器使用固态红外探测器，而Godart仪器使用鲁夫特探测器。两种仪器都易于使用，Datex体积小、重量轻，更是增添了便利。除了在Datex分析仪使用10%二氧化碳时，两种仪器的线性、稳定性、响应时间以及一氧化二氮的影响均在规格范围内。Godart仪器的线性明显优于规格中引用的1%满量程偏转（fsd），而Datex分析仪在2% fsd以内（使用10%二氧化碳时为4% fsd）。
