1. Device for the chemical or biochemical analysis of biological or chemical samples, notably for a comparative analysis of at least two samples, comprising multiple fractionation micro-columns (2) for the fractionation of sample components, each fractionation micro-column (2) comprising at least a micro-channel segment fitted with intermediate separation means, the microchannel segment comprising an inlet for the introduction of a sample-enriched mobile phase and an outlet for the evacuation of the fluids and situated at a teminal extremity, characterized by the fact that it comprises capture fluidic means (7), for the capture of the fractionated products, which are situated at the level of a terminal element of each fractionation micro-columns (2) and upstream from the evacuation outlet, by capture micro-channels which are used to collect the fractionation products and by groups of selective micro-cantilevers (13) which are associated with the fractionation micro-columns (2), are situated downstream from the capture micro-channels, a micro-cantilever (13) being fitted with detection means which are associated with analytical means.
