Abstract
A method and apparatus for the qualitative and quantitative detection of analytes is disclosed in which in the detection of an analyte in a sample, an elongated migration base is used, in which there is an area for binding a magnetically marked analyte, and in which, in stages the sample is absorbed into the migration base and the sample spreads on the migration base into the area. The elongated migration base is arranged in connection with a coil and a change in inductance, correlating with the content of the magnetically marked analyte, is detected.

A method for the qualitative and quantitative detection of analytes, in which in the detection of an analyte in a sample, an elongated migration base (14) is used, in which there is an area for binding a magnetically marked analyte, and in which, in stages
- the sample is absorbed into the migration base (14) and
- the sample spreads on the migration base (14) into the said area,
- characterized in that the elongated migration base (14) is arranged in connection with a coil (10.1) and a change in inductance, correlating with the content of the magnetically marked analyte, is detected.
An apparatus for the qualitative and quantitative detection of analytes, in which a magnetically marked analyte absorbed into a migration base (14) is arranged to be detected with the aid of coil devices which include,
- primary coil devices (11)
- devices (12) for supplying the said coil devices (11) with alternating current,
- secondary coil devices, which include an astatic pair of coils (10) that comprise at least two secondary coils (10.1, 10.2), arranged in connection with the primary coil devices (11), and
- devices (13) for observing the state of equilibrium of the said pair of coils (10),
- characterized in that at least one of the secondary coils (10.1) is arranged to have a shape that will receive the migration base (14) tightly inside it.
