Abstract

Un método para determinar la desviación del trayecto de un muestreo (610), el método que comprende: exponer la muestra (610) a radiación electromagnética a una pluralidad de números de onda, determinar la absorción electromagnética en la muestra (610) a una pluralidad de números de onda, determinar un primer número de onda asociado a un primer nivel de absorción de una banda de absorción y un segundo número de onda asociado a un segundo nivel de absorción de una banda de absorción, en donde el segundo número de onda es diferente del primer número de onda, determinar una diferencia entre el primer número de onda y el segundo número de onda, y determinar la desviación del trayecto sobre la base de la diferencia.
