Device for detection and measurement of a target compound such as a food toxin
First Claim
1. Apparatus for the detection or determination of a target comprising a target compound, a derivatised target compound or target compound-stimulated moiety, said apparatus comprising:
- means for mounting a sample cartridge, which sample cartridge comprises a packing or coating capable of immobilising or isolating the target in a layer or band,an excitation unit for emitting radiation that excites fluorescent radiation in the target,a detection unit that is sensitive to said fluorescence, andmeans for scanning the target with the detection unit, said means for scanning includingmeans for relatively moving the mounting means and the detection unit whereby the fluorescent radiation from the target may be sensed,said means for relatively moving the mounting means and the detection unit comprisingmeans for relatively moving the mounting means and the detection unit in such a manner as to scan the detection unit past all of the target,whereby the extent of the fluorescing target and the total fluorescence may be determined.

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.
