The multichannel capillary biosensor system includes a selecting valve system for selection of the sample or a reagent. The selecting valve system is connected to a second valve system accommodating a sensing channel and a first bypass channel. The second valve system is connected to a directing valve system having at least two positions, with a first position being connected to a second bypass channel and a second position being connected to a detector for detecting the analyte. The device has a pump connected at one end to the second bypass channel and the detector and at a second end to a waste vessel. The device also has a control system for controlling the device. The analyte can be selected from the group of microorganisms, macromolecules, and small molecules.

Versatile multichannel capillary biosensor system

A method for determining a concentration of a contaminant in a first sample, the method including producing the first sample, including adding a plurality of immuno-beads to a test substance; exposing a crystal microbalance immunosensor to the first sample; determining a change in a first motional resistance of the crystal microbalance immunosensor following exposure to the first sample (&#x394;R); and determining the concentration of the contaminant in the first sample according to &#x394;R.
