Abstract

UN ESPECTROMETRO CALIBRADO PUEDE DETERMINAR INDIRECTAMENTE UNA PROPIEDAD FISICA O QUIMICA DE UNA MUESTRA BASADA EN RESPUESTAS ESPECTRALES MEDIDAS POR EL ESPECTROMETRO RESPECTO DE LA MUESTRA PARTICULAR. ESTA INVENCION SE DIRIGE A UN METODO PPARA CALIBRAR O RECALIBRAR UN SEGUNDO ESPECTROMETRO EN LA LUZ DE UN PRIMER ESPECTROMETRO, O EN SI MISMO, RESPECTIVAMENTE. LA CALIBRACION EMPLEA UNA UNICA SELECCION Y MANIPULACION DE DATOS ESPECTRALES OBTENIDOS TANTO DEL PRIMER INSTRUMENTO COMO DEL SEGUNDO INSTRUMENTO. LA RECALIBRACION EMPLEA UNA UNICA SELECCION Y MANIPULACION DE DATOS ESPECTRALES DEL MISMO PRIMER INSTRUMENTO, QUE SE OBTIENE TANTO ANTES COMO DESPUES DE LA NECESIDAD DE RECALIBRACION. EN VEZ DE MODIFICAR LAS RESPUESTAS RESPECTIVAS DEL PRIMER Y SEGUNDO INSTRUMENTO, O EL PRIMER INSTRUMENTO ANTES Y DESPUES DE LA NECESIDAD DE RECALIBRACION, ESTA INVENCION MODIFICA LA ECUACION DE RECALIBRACION DEL SEGUNDO, O INSTRUMENTO O INSTRUMENTO RECALIBRADO, PPARA PRODUCIR RESULTADOS CONSISTENTES EN LOS OBTENIDOS POR EL PRIMER INSTRUMENTO, O EL PRIMER INSTRUMENTO ANTES DE SALIR DE LA CALIBRACION. UNA ECUACION DE CALIBRACION ES UNA ECUACION QUE TRANSFORMA LOS DATOS ESPECTRALES DE UNA MUESTRA PARTICULAR EN UNA VARIEDAD DE LONGITUDES DE ONDAS EN UN VALOR CALCULADO PARA UNA PROPIEDAD QUIMICA O FISICA. GENERALMENTE, LA FORMA DE TAL ECUACION DE CALIBRACION ES DE UNA COMBINACION LINEAL DE ABSORCION O TRANSFORMADAS MATEMATICAS DE ABSORCIONES MEDIDAS POR EL PRIMER Y EL SEGUNDO ELEMENTO PPARA CADA MUESTRA. SORPRENDENMENTE, Y ESTADISTICAMENTE CONFIRMADO, LA PRECISION DEL INSTRUMENTO CALIBRADO O RECALIBRADO SE MANTIENE Y DE ALGUNA MANERA SE MEJORA.
