Claim 21:
22. The system according to claim 16, further comprising at least one magnet which is movably arranged for being positioned at a first position corresponding to the position of the decoupler but on a side of the planar waveguide opposite to the side where the receptor molecules are arranged on the surface of the planar waveguide, at a second position also corresponding to the position of the decoupler but on the same side of the planar waveguide where the receptor molecules are arranged on the surface of the planar waveguide, or at a third position in which the magnet is arranged remote from the path of the coherent light from the light source to the grating as well as remote from the path of the collimated beam of diffracted coherent light from the planar waveguide to the detector, and remote from the path of the coherent light from the grating to the decoupler.
