Abstract
A slurry compressor for obtaining a homogeneous, pressurized, packed absorbent bed of slurry in a chromatographic column is provided. The compressor includes a solid first portion and a second portion which is a slightly tapering walled structure integral with the first portion. An annular groove is disposed within the first portion and a resilient O-ring sealing member is disposed within the ring. A split ring backup-spacer element can also be positioned within said groove to provide increased sealing to prevent leakage of the particles beyond the compressor element. An adapter element for enabling the insertion of the compressor into the column without damaging the surface of the O-ring is also disclosed. A handled straight adapter is also provided to enable the column to be supporting during packing and to be stabilized during column disassembly. A method of packing a column which includes shaking the slurry-filled column prior to pressurizing the column is set forth.
