[Method of separating volatile anesthetics from gaseous mixtures in which they are contained]

A technique for separating volatile anaesthetics from the gaseous mixtures in which they are contained is reported. It consists of the absorption of vapours by bubbling the mixture in fluid solvents belonging to the glycol group. The results show that the principles described can be applied in practice as the technique is able to ensure the almost complete absorption of anesthetic vapours for the duration of an operating session lasting five hours.
