Abstract: A laser induced breakdown spectroscopy (LIBS) analyser (10) comprises an optical path P (shown by dashed lines P1 and dash-dot lines P2) and an automatic focus (or tracking) system (12). The optical path P focuses a laser beam emitted from a laser (14) onto a portion of sample S which is to be analysed by the analyser (10), and focuses radiation emitted by the sample S when irradiated by the laser beam to a detector (16). The automatic focus system (12) is capable of varying a length of the optical path P to maintain a constant spatial relationship (i.e. distance) between a focal point (18) of the laser beam and the sample S; as well as maintaining a constant instantaneous field of view (IFOV) of the detector (16) on the focal point of the laser.

Abstract: A method of calibrating an emission spectrometer (10) having a detector (11) capable of detecting spectral components of incident radiation, and a measurement optical path (28) which directs an energy beam (26) to a sample (20) and radiation emitted by the sample when irradiated by the energy beam to the radiation detector (11). The method comprises directing radiation of known spectral characteristic along an alternate path to the detector (11). The detector (11) to detects spectral characteristics of the radiation and makes a comparison with the known spectral characteristics. Drift data is determined on a basis of any variation between the detected and known spectral characteristics. The drift data is stored and subsequently used to adjust detected spectral characteristics of a sample in the measurement optical path (28) produce a drift calibrated output spectral analysis of the sample.

Abstract: A method (10) for autonomously determining an elemental composition of an ore involves an initial step (12) of conveying a stream of the ore past a moisture measurement system and an analyser. At step (14) the moisture measurement system operates to obtain moisture content data of the ore. As the stream of ore subsequently passes the analyser, the analyser at step (16) operates to obtain raw elemental composition data of the ore. The moisture content data and the raw elemental composition data are provided as inputs to compensation step (18). In the compensation step (18) one or more data compensation or correction methods or techniques are performed to provide moisture corrected elemental composition data of the ore. This compensated data is provided at step (20).

Abstract: Un analizador de espectroscopia de plasma inducido por laser (LIBS) comprende una trayectoria optica P (mostrada por la linea de rayas P1 y la linea de rayas- puntos P2) y un sistema de enfoque (o seguimiento) automatico. La trayectoria optica P enfoca un rayo laser emitido desde un laser sobre una porcion de una muestra S que va a ser analizada por el analizador, y enfoca la radiacion emitida por la muestra S cuando es irradiada por el rayo laser a un detector. El sistema de enfoque automatico es capaz de variar una longitud de la trayectoria optica P para mantener una relacion espacial constante (es decir, una distancia) entre un punto de enfoque del rayo laser y la muestra S; asi como mantener un campo de vision instantaneo constante (IFOV) del detector sobre el punto focal del laser

EL DETECTOR DETECTA CARACTERISTICAS ESPECTRALES DE LA RADIACION Y REALIZA UNA COMPARACION CON LAS CARACTERISTICAS ESPECTRALES CONOCIDAS. LOS DATOS DE DESPLAZAMIENTO SE DETERMINAN EN FUNCION DE CUALQUIER VARIACION ENTRE LAS CARACTERISTICAS ESPECTRALES CONOCIDAS Y LAS DETECTADAS. LOS DATOS DE DESPLAZAMIENTO SE ARCHIVAN Y POSTERIORMENTE SE UTILIZAN PARA AJUSTAR LAS CARACTERISTICAS ESPECTRALES DETECTADAS DE UNA MUESTRA EN EL PASO OPTICO DE MEDICION PARA OBTENER UN ANALISIS ESPECTRAL DE LAS SENALES CALIBRADAS PARA EL DESPLAZAMIENTO DE LA MUESTRA. SU APLICACION PERMITE DETECTAR LA COMPOSICION ELEMENTAL DE UNA MUESTRA
