Patent ID: 8865068

Claim:
An apparatus for analysis of an analyte in a mixture of biological components, chemical components, or both biological and chemical components, having: the analyte having magnetic particles attached thereto either directly or indirectly through an intermediate material and being spatially arranged in a prescribed manner in a probe volume; a magnetic field generator, within which action said magnetic particles are situated, the magnetic field generator generating a magnetic field, the magnetic field having a spectrum, the spectrum being pre-set with spectral components at least at two frequencies; a meter of the magnetic induction produced by said magnetic particles; an output signal receiver; a block generating a result of analyses, an input of said block is connected to the output of the output signal receiver, and a radio-frequency filter, which input is connected to the output of the magnetic induction meter, and the output of the filter is connected to the output signal receiver, the filter being tuned to pass the signal at a picked-out frequency, which is a linear combination of the frequencies of said spectral components.
