ABSTRACT:
Analytical apparatus and methods for processing multiple samples simultaneously. Radiation such as laser light desirably including plural wavelengths is directed through multiple samples simultaneously, as by directing a beam of radiation along a single path through all of the samples. Response to each wavelength is monitored by monitoring an induced effect, other than the intensity of the applied radiation itself. Useful signal-to-noise ratios are obtained with low absorption in each sample. One sample desirably is of known composition, and serves as an internal calibration standard.
