Abstract: A device for detection of magnetic permeability (?) or, alternatively, relative magnetic permeability (?r) or, alternatively relative magnetic susceptibility (?r-) of a sample is described. The device comprises a sample chamber having at least one opening for introduction of a sample or a sample container holding a sample and an electronic circuit. The device also comprises a coil surrounding said sample chamber, and also an electronic circuit adapted to measure the inductance of said coil. The sample chamber, coil and at least one component of the electronic circuit are placed in a temperature controlled zone. Said at least one component in said electronic circuit is/are selected from the group consisting of capacitors, sensors, precision voltage references, precision regulators, low pass and or high pass filters.

Abstract: The present invention generally relates to the determination of an analyte concentration (quantitative determination) or whether an analyte threshold level has been passed (qualitative determination) in a biological sample through employment of a disposable analytical microprocessor device. The device can include a batch-specific, self-executable algorithm for the calculation of the analyte concentration.

Abstract: A device for biochemical processing and analysis of a measured sample volume of a sample is described. The device is characterized in that it consists of a sealed vessel (1) and that it comprises at least one thin pierceable membrane (2) through which a capillary tube (3) containing said measured sample volume of a sample can pass into said sealed vessel (1). Said sealed vessel (1) further contains at least one biochemically reactive substance (4) and a liquid (6). A method, wherein the device according to the invention is used for analysis, is also described.

Abstract: A device including a sample compartment, a coil and an arm for mechanical manipulation of a sample vessel placed in the sample compartment and containing a sample is described. In at least one embodiment, the coil is surrounding the sample compartment and the sample compartment has an opening for insertion and removal of the sample vessel. A method, using the device according to at least one embodiment of the invention for detection of magnetic permeability, relative magnetic permeability or relative magnetic susceptibility, is also described.

Abstract: A device for detection of magnetic permeability ? or, alternatively, relative magnetic permeability ?r or, alternatively, relative magnetic susceptibility (?r?1) of a sample, wherein said device contains a sample chamber and at least two coils, one coil surrounding said sample chamber and one coil placed so as to be in thermal contact by being physically connected to the material which constitutes the sample chamber, but without surrounding the cavity of the sample chamber, said sample chamber having at least one opening for introduction of a sample or a sample container holding a sample, said device also provided with an electronic circuit which measures the difference in inductance between the two coils.
