Abstract

Se describen artículos y métodos para la deteccion y/o cuantificacion de substancias orgánicas a analizar. La solicitud provee una tira de prueba indicadora química que comprende: un substrato; y un recubrimiento que comprende un complejo de leuco- colorante sobre el substrato, siendo el recubrimiento insoluble en agua y reactivo con una substancia orgánica a analizar, derivándose el recubrimiento de una solucion de leuco-colorante y agente revelador. En otro aspecto, el recubrimiento comprende además un adyuvante en forma de un material aprotico hidrofobo, polar, insoluble en agua que extiende el límite inferior de deteccion para la substancia a analizar. En otro aspecto, la presente provee un método de uso de una tira de prueba indicadora química, que comprende: (a) exponer la tira de prueba indicadora química a una muestra líquida que comprende una substancia orgánica a analizar; (b) medir un cambio de color en la tira de prueba indicadora química después del paso de exposicion; y (c) correlacionar el cambio de color con la concentracion de la substancia a analizar en la muestra.Articles and methods for the detection and / or quantification of organic substances to be analyzed are described. The application provides a chemical indicator test strip comprising: a substrate; and a coating comprising a leuco-dye complex on the substrate, the coating being insoluble in water and reactive with an organic substance to be analyzed, the coating being derived from a leuco-dye solution and developer. In another aspect, the coating further comprises an adjuvant in the form of a hydrophobic, polar, water insoluble aprotic material that extends the lower limit of detection for the substance to be analyzed. In another aspect, the present provides a method of using a chemical indicator test strip, comprising: (a) exposing the chemical indicator test strip to a liquid sample comprising an organic substance to be analyzed; (b) measure a color change in the chemical indicator test strip after the exposure step; and (c) correlate the color change with the concentration of the substance to be analyzed in the sample.
