Abstract: A cartridge is adapted to house at least one biological sample therein, where the cartridge contains at least two overlapping layers, and the layers include at least one layer of highly hydrophobic, inert, and biocompatible material, with contact angle ?c?90°, hydrophobic layer, and optionally, at least one layer of double-sided adhesive material, where in the absence of the at least one layer of double-sided adhesive material, the overlapping layers are connected together by chemical and/or physical bonding, where each of the overlapping layers has at least one inner hole that is pervious when the layers overlap one another, and the at least one inner hole is closed by the at least one biological sample, where loaded in the cartridge.

Abstract: Apparatus (100) for the quantification of biological components (3, 3?, 3?) in a fluid comprising: a measurement cell (1) comprising detection electrodes (4, 4?, 5, 5?, 6, 6?, 34, 34?, 84, 84?, 94, 94?, 184, 184?, 194, 194?) and reference electrodes (7, 7,? 8, 8?, 9, 9?, 37, 37?, 64, 64?, 74, 74?, 164, 164?, 174?); an electronic unit (201) for the generation of input signals, impedimetric measurement, amplification of output signals and communication with a user interface; means for the generation of a magnetic field (101, 102, 103) with an appropriate gradient that can be modulated in time, said means of magnetisation being configured to generate a magnetic field capable of causing, in combination with concentrators (10, 10?, 10?, 14, 14?, 14?, 15) housed in the measurement cell, the separation of the components (3, 3?, 3?) to be quantified from the rest of the solution and their concentration on the detection electrodes (4, 4?, 5, 5?, 6, 6?, 34, 34?, 84, 84?, 94, 94?, 184, 184?, 194, 194?).
