Abstract
Disclosed is an apparatus for analysis of a mixture of biological and/or chemical components that exposes a spatially arranged chosen component attached to magnetic particles to a magnetic field and records a magnetic induction signal from which the content of the biological and/or chemical components is determined. The magnetic field is alternating and has a pre-set spectrum at least at two frequencies. The apparatus records the signal at a frequency which is a linear combination of the at least two frequencies while the magnetic particles are exposed to the magnetic field.

15. An apparatus for analysis of a mixture of biological and/or chemical components, having:
-
a chosen component of the mixture being analysed, said component being spatially arranged in a prescribed manner; magnetic particles attached to the chosen component of the mixture being analysed, directly or through an intermediate material; a magnetic field generator, within which action said magnetic particles are situated; a meter of the magnetic induction produced by said magnetic particles; an output signal receiver; a block generating the result, which input is connected to the output of the output signal receiver, wherein the chosen component of the mixture being analysed with magnetic particles attached to this component is grouped in a probe volume; the magnetic field generator is made so as to allow presetting the frequency spectrum of the magnetic field with spectral components, at least, at two frequencies; a radio-frequency filter is included, which input is connected to the output of the magnetic induction meter, and the output of the filter is connected to the output of the 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. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44)
