ABSTRACT:
An improved apparatus for protection of a liquid chromatography column is proposed. Under environmental changes in pressure and temperature, a liquid and a gas in a non-expandable container communicated with the chromatography column change their relative volume, so that the environmental changes are not transmitted to the column. To prevent the gas from entering into the column, a conduit connecting the column and the container enters into interior of the container.
