DEVICE AND METHOD FOR SEPARATING ANALYSING, DETECTING AND/OR DETERMINING? PARTICLES IN A LIQUID SAMPLE FLOW

摘要

A device for separating, analysing, detecting and/or determining particles in a liquid sample flow, particularly a microchip (1), wherein the device (1) comprises: -at least one sample flow separation area (4); -a sample flow supply (2) to supply the sample flow (S) to said sample flow separation area (4); and -at least one field generator (5, 6) which is configured to generate a field to substantially laterally separate certain sample flow particles when the sample flow flows through said separation area (4), for example via separation by free flow electrophoresis, free flow isoelectric focusing and/or isotachophoresis ; wherein the device is provided with an at least 2-dimensional detection pattern (9) located at least partly in and/or downstream with respect to said separation area (4), wherein said detection pattern (9) is suitable to interact with certain sample flow particles to be detected and/or determined. The invention also provides a method for separating, analysing, detecting and/or determining particles in a liquid sample flow.
