STERILISING AND DESORBING PROCEDURES AND EQUIPMENT

摘要

A steriliser apparatus includes a chamber in which an article or material to be sterilised is placed and a sterilising gas or vapour is then introduced into the chamber to contact and sterilise the article or material. The free sterilant gas or vapour in the chamber is removed and the article or material subjected to a desorbing step during which the concentration of sterilising gas or vapour in the chamber is measured by a sampling device in which a sample of chamber atmosphere is exposed to microwave radiation and the absorption spectrum monitored to determine the concentration of sterilising gas or vapour present in the chamber.
