Abstract

Un método para mejorar la sensibilidad de las mediciones en un Espectrómetro de Infrarrojos con Transformada de Fourier de trayectoria abierta llevando a cabo un desplazamiento del número de onda correctivo en el espectro de los elementos que se van a analizar dentro de una anchura de banda del espectrómetro, comprendiendo el método las etapas de: a) seleccionar una pluralidad de componentes conocidos dentro de una región espectral definida; b) medir la longitud de onda de cada uno de la pluralidad de componentes seleccionados; c) determinar un desplazamiento de número de onda para cada uno de la pluralidad de componentes medidos comparando los valores medidos con los valores de referencia; d) determinar un centro estadístico de la pluralidad de desplazamientos del número de onda determinados en la etapa c; e) generar una línea de corrección de desplazamiento del número de onda a través del centro estadístico de la etapa d) y delorigen definido por un número de onda 0, por una corrección 0; y f) corregir las mediciones del espectrómetro posteriores desplazando la longitud de onda medida según la línea de corrección de desplazamiento del número de onda determinada en la etapa e).
