Patent

CA 2652382

An apparatus is provided that includes a light emitting component, a light detecting component, a lock in amplifier, a frequency generator that is operatively linked to the lock in amplifier and the light emitting component, a speaker capable of emitting an audio signal wherein the output audio signal varies depending on the detected fluorescence in the sample, and a visible output of relative fluorescent intensity where the visible output varies depending on the detected fluorescence in the sample. The apparatus may also include a laser that is operatively coupled to the lock in amplifier through a control switch, and focusing lens or an additional type of filter such as an interference filter, a short pass filter, a notch filter, a long pass filter or an infrared filter. The apparatus may be used to identify and/or to remove fluorescent or non fluorescent material from a sample. Associated methods are also disclosed.

L'invention concerne un appareil qui comprend un composant électroluminescent, un composant de détection de la lumière, un amplificateur enclenché, un générateur de fréquence qui est raccordé fonctionnel à l'amplificateur enclenché et au composant électroluminescent, un haut-parleur capable d'émettre un signal audio, le signal audio produit en sortie variant en fonction de la fluorescence détectée dans l'échantillon, et une sortie visible de l'intensité fluorescente relative, la sortie visible variant en fonction de la fluorescence détectée dans l'échantillon. L'appareil peut également comprende un laser couplé fonctionnel à l'amplificateur enclenché par le biais d'un commutateur de commande et une lentille de focalisation ou un genre supplémentaire de filtre tel qu'un filtre d'interférence, un filtre passe-court, un filtre coupe-bande, un filtre passe-long ou un filtre à infrarouge. L'appareil peut être utilisé pour identifier et/ou pour éliminer le matériau fluorescent ou non fluorescent d'un échantillon. L'invention décrit également des procédés associés.
