Analysis of anaesthetic gas mixtures of halothane (isoflurane or enflurane), N2O, air and CO2 by dual column gas-solid chromatography

Abstract

A dual column gas-solid chromatography is described for the separation and quantitative analysis of anaesthetic gas mixtures of halothane (isoflurane or enflurane), nitrous oxide, air and carbon dioxide. The separation was performed on two Chromosorb 101 columns (2 m and 2 m + 2 m). The second column was placed outside the oven and operated at room temperature.
