Abstract
Systems and methods for the rapid and reliable detection of analytes in liquid solutions such as water, drinking fluids, extracts of solids such as foods, soils, industrial fluids such as oils, cooling water, fuels, solutions of drugs or chemicals, etc. The systems preferably include an inexpensive and disposable capillary containing a dry chemical system of detection that reacts chromogenically or in other manner to indicate the presence of the analyte.
Claims44
A detection device for sensing the presence and identity of at least one analyte in a liquid sample, said detection device comprising:
- a capillary tube;
- one or more porous support layers packed consecutively in the tube;
- and
- porous plugs at the entrance to the tube and optionally between the various layers;
- at least one layer within the capillary which can interact with at least one analyte present in a test solution or with reaction products of said analyte to form a measurable detectable phenomenon such as a color change or fluorescence.
