Title
(EN) DEVICE FOR DETECTION AND MEASUREMENT OF A TARGET COMPOUND SUCH AS A FOOD TOXIN
(FR) DISPOSITIF PERMETTANT LA DETECTION ET LA MESURE D'UN COMPOSE CIBLE TEL QU'UNE TOXINE ALIMENTAIRE
Abstract
(EN)
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.
(FR)
La présente invention concerne un dispositif comprenant un support pour un échantillon, lequel comprend une garniture ou une enveloppe capable d'immobiliser ou d'isoler un composé cible dans une couche ou une bande; un bloc d'excitation qui émet des rayonnements qui excitent la fluorescence dans un composé cible ou un composé cible dérivé immobilisé ou isolé dans la garniture ou l'enveloppe, ou dans un autre fragment stimulé par le composé cible; un bloc de détection qui est sensible aux rayonnements émis par un composé cible fluorescent, un dérivé fluorescent ou un fragment stimulé par un composé cible fluorescent, et qui produit un signal proportionnel à la quantité de rayonnements détectée; un moyen permettant un déplacement relatif de la cartouche d'échantillons et du bloc de détection ainsi que la détection des rayonnements; et un bloc de traitement qui transforme la sortie du bloc détecteur un une valeur lisible associée à la quantité de composé cible immobilisée dans la couche ou la bande.
