Abstract

Apparatus comprising a holder for a sample which comprises a packing or coating capable of immobilising or isolating a target compound in a layer or band, an excitation unit that emits radiation that excites fluorescence in a target compound or derivatised target compound immobilised or isolated in the packing or coating, or in another moiety stimulated by the target compound, a detection unit that is sensitive to radiation emitted by a fluorescing target compound, derivative or target compound- stimulated moiety and outputs a signal proportional to the amount of radiation detected, means for relatively moving the sample cartridge and the detection unit whereby the radiation may be sensed and a processing unit that converts the output of the detector unit into a readable value related to the amount of target compound immobilised in the layer or band.
