20100209299 | METHOD OF ANALYSIS OF A MIXTURE OF BIOLOGICAL AND/OR CHEMICAL COMPONENTS WITH THE USE MAGNETIC PARTICLES AND APPARATUS FOR ITS EMBODIMENT - 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. | 08-19-2010 |
