Abstract
A filtration column assembly is provided for use in combination with a disposable cartridge of a diagnostic assay system. The filtration column assembly includes a column matrix material configured to filter a fluid sample, a tubular column configured to sealably engage a filtration chamber of the disposable cartridge and a cap configured to be inserted into an end of the tubular column and define a passageway to direct the sample fluid from the second end of the tubular column into a collection cavity disposed adjacent the filtration chamber. The tubular column defines (i) a column cavity for receiving the column matrix material, (ii) a first end having an opening for receiving the fluid sample and configured to retain the column matrix material, and (iii) a second end, receiving the fluid directing cap, and having an opening to dispense a filtered fluid sample from the column cavity.
