Title (EN) SYSTEM FOR ANALYZING CHEMICAL AND BIOLOGICAL SAMPLES
(FR) SYSTEME D"ANALYSE D"ECHANTILLONS CHIMIQUES ET BIOLOGIQUES
Abstract: front page image
(EN)A method and apparatus are provided for analyzing chemical and biological samples, comprising at least one slide (12, 14) having an electrically conductive surface (16, 18) thereof; a sample (24) to be analyzed; means (10, 20) to induce an electro-static field in said sample to cause particles within said sample to selectively re-orient themselves or migrate to a new position; and means (22) to analyze said migrating particles. In one embodiment an electrical field activates a nematic fluid stain (47) for identification of particles within a sample. By altering the electrical characteristics of a sample and passing an electrical waveform through the sample, the resultant change in waveform is indicative of the sample"s constituency.
(FR)Methode et appareil d"analyse d"echantillons chimiques et biologiques comprenant au moins une lamelle (12, 14) ayant une surface electriquement conductrice (16, 18), un echantillon (24) a analyser, des moyens (10, 20) d"induction d"un champ electrostatique dans l"echantillon pour forcer les particules dudit echantillon a se reorienter selectivement ou a emigrer dans une nouvelle position, et des moyens (22) d"analyse desdites particules migratrices. Dans une realisation, un champ electrique active un colorant fluide nematique (47) qui identifie les particules dans l"echantillon. En modifiant les caracteristiques electriques d"un echantillon et en faisant passer une onde electrique a travers l"echantillon, le changement resultant dans l"onde indique la composition de l"echantillon.
