Claims20
A chromatography column comprising a tubular wall structure having a first end, a second end, an inner wall surface facing an interior of the tubular wall structure, and an outer wall surface, said tubular wall structure comprising a fiber-reinforced layer.
A method of analyzing a test sample that potentially contains at least one analyte, said method comprising the steps of:
- introducing the test sample into a chromatography column containing a rigid support media, said rigid support media comprising a plurality of inorganic particles, wherein said chromatography column comprises a tubular wall structure comprising a fiber-reinforced layer.
A chromatography column comprising:
- a column inlet at a first end of the column, said column inlet having an inlet cross-sectional flow area;
- a column outlet at a second end of the column opposite the first end, said column outlet having an outlet cross-sectional flow area;
- and
- a tubular wall structure extending between the column inlet and the column outlet, said tubular wall structure having a tubular cross-sectional flow area that is substantially constant along a length of the tubular wall structure and is substantially equal to the inlet cross-sectional flow area, the outlet cross-sectional flow area, or both;
- wherein said tubular wall structure comprises:
- an outer fiber-reinforced layer;
- and
- an inner metal layer.
