title: Gas-solid chromatography of isopropyl alcohol samples.
abstract: A study was conducted to analyze the accuracy of the procedure used by a hospital pharmacy to make solutions of 70% isopropyl alcohol and to determine the amount of evaporation of the alcohol which may take place when the containers of these solutions are repeatedly opened. Twenty-five samples of 70% isopropyl alcohol were obtained from eight hospital wards. All the containers had been in patient care areas for over one month and were less than one-half full. Six of the samples were randomly chosen for gas-chromatographic analysis. The results show that gas chromatography for the quantitative analysis of isopropyl alcohol is highly reliable and suitable for the analysis of very large or very small samples. There was no significant amount of evaporation of isopropyl alcohol despite the length of time the solutions had been on the hospital wards.
