Abstract

SE PRESENTA UN METODO PARA MEJORAR LA EXACTITUD DE LOS ENSAYOS DE DIAGNOSTICO SENSIBLES A LA TEMPERATURA QUE SE LLEVAN A CABO UTILIZANDO ESPECTROMETROS DE REFLECTANCIA PARA DETECTAR LOS CAMBIOS DE COLOR EN UN SISTEMA DE PRUEBA SOLIDO QUE HA SIDO PUESTO EN CONTACTO CON UN SISTEMA DE PRUEBA FLUIDO QUE SE SOSPECHA QUE CONTIENE UN ANALITO CUYA PRESENCIA Y/O CONCENTRACION ESTA SIENDO DETERMINADA. LA MEJORA COMPRENDE LA DETERMINACION DE LA TEMPERATURA DEL MATERIAL DE PRUEBA SOLIDO MEDIANTE LA MEDICION DE LA REFLECTANCIA DE UN CRISTAL LIQUIDO TERMOCROMICO PEGADO A DICHO MATERIAL Y LA CORRECCION DEL RESULTADO DEL ENSAYO EN FUNCION DE UN CAMBIO EN LA TEMPERATURA A PARTIR DE UNA TEMPERATURA NOMINAL PRESELECCIONADA.
