METHOD OF ANALYSIS AND ANALYTIC DEVICE Russian patent published in 2015 - IPC G01N33/543 

FIELD: chemistry.

SUBSTANCE: group of inventions relates to an analysis of liquid samples. Claimed is a method of analysis of at least two analytes in a liquid sample; the said method contains the following stages: supply of a substrate, where at least two different types of binding molecules are immobilised on the substrate and where each type of the binding molecules possesses specific affinity to analyte, b) bringing the sample in contact with the said binding molecules, c) realisation of the contact between the binding molecules and a labelled identifiable molecule with specific affinity to analyte for at least one analyte to be analysed, and realisation of the contact between the binding molecules and a labelled version of analyte for at least one other analyte to be analysed, and d) measurement of an identified signal from the labelled identifiable molecule and labelled analyte on the substrate, where the concentration of the labelled analyte is selected in accordance with the analyte concentration in the sample. An analytic device is also claimed.

EFFECT: simplification and increase of the analysis reliability is achieved.
