(57) [Summary]nMethods and apparatus for performing chemical analysis (eg, devices, systems, test kits). a) Analytical systems that can use a membrane to separate selected analytes from other substances present in complex substrates (eg, foods, oils, pharmaceutical / cosmetic preparations, biological fluids, etc.) (eg, , A test kit comprising devices, membranes, and reagents) and b) an analytical device (eg, sample processing) that can be used to qualitatively or quantitatively determine one or more analytes present in the composite substrate. Other hardware components associated with the device and membrane), c) analytical methods for qualitatively or quantitatively determining one or more analytes present in the composite matrix, and d) specific analytes. And a new chemical test method for determining qualitatively and / or quantitatively. |
