Analytical apparatus and methods for processing multiple samples simultaneously. Radiation such as laser light desirably including plural wavelengths (12, 14) is directed through multiple samples (32 a-d) simultaneously, as by directing a beam of radiation along a single path through all the samples. Response to each wavelength is monitored by monitoring an induced effect, other than the intensity of the applied radiation itself (42). Useful signal to noise ratios are obtained with low absorbance in each sample. One sample desirably is of known composition, and serves as an internal calibration standard.
L'invention concerne un appareil analytique et des procédés de traitement simultané d'échantillons multiples. Un rayonnement tel qu'une lumière laser comprenant de préférence plusieurs longueurs d'ondes (12, 14) est dirigé au travers d'échantillons multiples (32a-d) simultanément en envoyant un rayon de radiation sur un seul trajet au travers de tous les échantillons. La réponse à chaque longueur d'ondes est contrôlée par contrôle d'un effet induit, à l'exclusion de l'intensité du rayonnement appliqué (42). Des rapports utiles signal/bruit sont obtenus avec une faible absorbance dans chaque échantillon. Un échantillon possède de préférence une composition connue et sert d'étalon de calibrage interne.
