According to an example aspect of the present invention, there is provided a hyperspectral light source system, comprising a broadband light source arranged to generate and radiate a broadband light signal, a rotating multi bandpass filter arranged to pass through a part of the broadband light signal on one of multiple passbands of the hyperspectral light source system, wherein a rotation angle of the rotating multi bandpass filter determines the part of the broadband light signal that passes through the rotating multi bandpass filter and a tunable filter adjusted to pass through the part of the broadband light signal, coming from the rotating multi bandpass filter, on said one passband of the hyperspectral light source system.

A microfluidic chip device (MCD) and its use for performing miniaturized assays on magnetic microbeads (MMs) are described. The MCD is particularly useful for carrying out miniaturized transcript analysis by aiding affinity capturing (TRAC) assays, including PCR. The MCD comprises at least one reaction chamber with sealable liquid connections and at least one fluidic pillar filter in each chamber. The fluidic pillar filter comprises rods with spacings allowing MMs to pass. The sealable liquid connections feed liquid to the reaction chamber, wherein air bubbles are removed. The liquid stream contacts the MMs, which are manipulated with a magnetic rod. The liquid connections enable trapping of the MMs behind the pillar filters or in the channel, while the liquid is changed.
