Patent ID: 8790917

Claim:
A detection method, comprising: placing a device containing a measured sample volume of a sample in or in an immediate vicinity of an electric coil for detection of magnetic permeability μ, relative magnetic permeability μ r , or relative magnetic susceptibility (μ r −1); and performing at least one selected from biochemical processing and analysis of the measured sample volume of a sample, wherein the device includes, a sealed vessel, the sealed vessel containing a liquid and at least one biochemically reactive substance, at least one thin pierceable membrane through which a capillary tube containing said measured sample volume of a sample can pass into said sealed vessel, and a capillary holder with an arm, in which said capillary tube is to be mounted and by means of which said capillary tube is to be inserted through said at least one thin pierceable membrane into said sealed vessel, wherein said arm has one selected from a conically shaped thickening on an outer diameter and a collar by which an opening of said at least one thin pierceable membrane is sealed after the insertion of the capillary tube, and wherein said sealed vessel further contains one selected from at least one marker substance and carrier particles forming a bottom sediment.
