Abstract
Un sistema (102) para determinar las propiedades de una muestra que comprende un detector de LIBS (104, 106), que tiene un láser (104) para la ablación de una porción de la muestra y un espectrofotómetro óptico (106) para generar datos de LIBS que representan una variación de intensidad dependiente de la longitud de onda en la energía óptica emitida desde la porción separada; un detector de absorción de infrarrojos (108, 110), que tiene una fuente de energía infrarroja (108) para iluminar al menos una porción de la muestra con energía infrarroja y un espectrofotómetro óptico (110) para generar datos de iluminación que representan una variación de intensidad dependiente de la longitud de onda de la energía infrarroja después de su iluminación de la muestra; al menos un modelo de predicción quimiométrica en una forma utilizable por un procesador de datos (112) y cada modelo de predicción quimiométrica construido para vincular características tanto de datos de LIBS como de datos de iluminación a una propiedad específica diferente de la muestra; y un procesador de datos (112) configurado para recibir los datos de LIBS y los datos de iluminación, para construir un conjunto de datos combinado derivado de al menos una porción de los datos de LIBS y al menos una porción de los datos de iluminación, y para aplicar al menos un modelo de predicción quimiométrico al conjunto de datos combinado para generar a partir del mismo una determinación de la propiedad específica vinculada por el modelo de predicción.
Description
se calibró el TOC fue el método de combustión en seco en el que se controla la cantidad de CO2 liberada para una muestra de suelo calentada. En el presente ejemplo se midieron las mismas ciento seis muestras de suelo de calibración utilizando el sistema descrito en general con relación al de la figura 1. Una vez más, se emplearon los conjuntos de datos combinados de cincuenta muestras para establecer un modelo de predicción PLS y los conjuntos
5 de datos combinados de los restantes cincuenta y seis se emplearon como el conjunto de datos de validación.
El modelo de predicción PLS generado a partir de la curva ilustrada en la figura 6 que emplea el conjunto de datos combinado tiene una precisión de predicción de 0,678 (en comparación con la precisión de referencia de 0,7) y una correlación de 0,79.
10 Otros modelos de predicción para propiedades del suelo, tales como la capacidad de intercambio catiónico o "CEC" (una predicción cuantitativa típicamente expresada en cmol(+)/kg), contenido de calcio o potasio (predicciones cuantitativas expresadas típicamente en partes por millón "ppm"), pueden construirse de una manera similar y algunos o todos ellos pueden ponerse a disposición del procesador de datos 112 de la figura 1 para su aplicación a
15 conjuntos de datos combinados obtenidos para muestras de suelo desconocidas usando un sistema de acuerdo con la presente invención, tal como el ilustrado en la figura 1.
Por lo tanto, a través del presente ejemplo, se ha ilustrado que el sistema de acuerdo con la presente invención puede utilizarse para realizar mediciones cuantitativas incluso en una matriz de muestra muy compleja.
20 Se apreciará que mientras que el sistema y el método de acuerdo con la presente invención tienen una aplicación particular en el análisis de suelos, la presente invención no pretende limitarse a su uso en este campo. De hecho, la presente invención puede encontrar usos y traer sus ventajas a diversos campos tales como la detección de explosivos u otra amenaza; vigilancia o control de alimentos, bebidas y piensos; y las investigaciones de fluidos
25 biológicos. También se apreciará que la elección de la metodología de análisis no está limitada a PLS, sino que, como se conoce en la técnica de la quimiometría, puede seleccionarse después de una consideración de uno o más de, por ejemplo, la linealidad del conjunto de datos, en el tamaño y diversidad de ese conjunto de datos y si es necesario una predicción cuantitativa o cualitativa.
