Abstract: The invention relates to devices and methods for chemical analysis, specifically to devices for extracting molecules, e.g. biomolecules such as peptides, and/or proteins, from a mixture of molecules in a solution and performing sample treatment on the extracted molecules before presenting them to an analysis instrument. The method for analysis of samples uses a combined sample treatment and sample carrier device. Said device comprises a plate with inlets at one side connected to respective compartments situated at respective array positions for receiving samples to be treated and analysed, each compartment being in communication with an outlet enabling fluid flow through the plate.

Abstract: A processing module for extracting certain biomolecules from a solution, comprising an extraction unit having at least one elongated channel (101) each of said at least sine channel have un inlet (102) and an outlet (103) and being provided with adhering units (201), each said unit being provided with adhesive means, having affinity for said certain biomolecules, said extraction unit further comprises docking means (205) having an inlet array and an outlet array, that enables the extractor to be docked to and undocked from other devices having corresponding docking means, such that said solution or another fluid can be made to flow from said other devices, entering the inlet array, to flow through the at least one channels(101) and to leave the extraction device via the outlet array.
