Abstract

A first apparatus (100) for processing a liquid sample is disclosed. The apparatus (100) includes a sample-receiving (120), a filtrate-receiving component (150), and an analyte-capture element (170). The apparatus (100) forms a liquid flow path through which the sample passes, thereby causing the analyte-capture element (170) to capture an analyte, if present. A method is disclosed whereby a liquid sample is passed through the first (100) apparatus and the analyte-capture element (170) is easily separated from the apparatus for further processing and detection of the analyte. A structurally-related second apparatus (200) for processing a plurality of liquid samples, and a corresponding method of use, also is disclosed.

Description

[0001] Cross references to related patent applications [0002] This patent application claims the benefit of US Provisional Patent Application No. 61 / 451,096, filed March 9, 2011, which is hereby incorporated by reference in its entirety. Background technique [0003] Many types of samples (such as clinical, environmental, food and beverage samples) are routinely tested for the presence of microorganisms. Specifically, various samples are tested to determine the presence of pathogenic microorganisms. Typically, various types of pretreatment of the sample (i.e., treatment prior to the detection step) are required to increase the number of target microorganisms, reduce the number of non-target microorganisms, concentrate microorganisms, and / or reduce the concentration of potential interfering substances in the sample. quantity. The preprocessing steps can be laborious and can take hours to days to complete. Various materials and devices have been developed to reduce the num...
