ABSTRACT:
The present application relates to a chemical sensing device for detecting an analyte in a liquid sample containing suspended particles. The device comprises a radiation source adapted to generate electromagnetic radiation, a transducer (3) having a pyroelectric or piezoelectric element and electrodes which is capable of transducing a change in energy to an electrical signal, at least one reagent (2) on or proximal to the transducer (3), the reagent being capable of absorbing the electromagnetic radiation to generate energy when in contact with the analyte, a chamber (9) for holding the sample in fluid contact with transducer, and a detector which is capable of detecting the electrical signal generated by the transducer. The transducer is in a plane from +45° to −45° to the vertical.
