A chromatography column for effecting chromatographic separation of at least two components of a sample flowing through the column. The column comprises a housing and at least one solid stationary phase within the housing. The stationary phase has chromatographic functionality and is effective for chromatographic separation. Means are provided for distributing the sample through the stationary phase and for collecting the sample after the sample has flowed through the stationary phase. The stationary phase comprises:

Chromatography column

A chromatography column for effecting chromatographic separation of at least two components of a sample flowing through the column. The column comprises a housing and at least one solid stationary phase within the housing. The stationary phase has chromatographic functionality and is effective for chromatographic separation. Means are provided for radially distributing the sample through the stationary phase and for collecting the sample after the sample has flowed through the stationary phase. The stationary phase comprises:

A deformable liquid filter with means for purging air and gases having a housing with spaced flexible walls and a hydrophilic membrane defining a collapsible inlet chamber with air and gas vent means on one side of the membrane and an outlet chamber on the opposite side of the membrane with membrane support means which prevents the outlet chamber from collapsing.

Filter and method of making same

Dry forming the peripheral portion of discs of filter media to suppress edge leakage in filter presses.
