Abstract: In a spectroscopic process a sample for producing a test spectral line or spectrum of at least one component contained in the sample is stimulated and the transmitted and/or emitted electromagnetic rays are used to create the test spectral line or spectrum. In order to improve such a spectroscopic process to such an extent that variations of certain parameters, which alter the shape and/or occurrence of a spectral line, are compensated, a comparison spectral line or spectrum of a known comparison material is produced under substantially the same parameters as the sample. The comparison spectral line or spectrum is compared with an ideal comparison spectral line or spectrum in order to calculate a transfer function, and the transfer function is applied to the test spectral line or spectrum in order to calculate a corrected test spectral line or spectrum.

Abstract: Atom absorption spectroscopy method generates at least one first beam of monochromatic radiation at a certain wavelength. Radiation is separated into a test beam and a reference beam, and only the test beam is led through a test area. Subsequently, both beams pass through a slot system into a monochromator, and after their spectral breakdown, reach a detector system. In order to improve such atom absorption spectroscopy method in a way that allows the test beam and the reference beam as well as their spectra to be guided close to, or adjacent to one other onto the detector system, and, at the same time enables a simple and easy adaptation of the spectrometer's effective spectral range to a monochromator's characteristics, the test beam and the reference beam thus pass through different slots in the slot system and are projected onto essentially spatially separate areas of the detector system, with their spectra's broken-down.

Abstract: A light source for an atomizing device, specifically an atom absorption spectrometer comprising one, two, or more lamps, whose ray can be selected by means of at least one two-dimensionally moveable optical selection element, and which can be directed in the direction of atomizing device. Fine-tuning is thereby achieved quickly with little constructive expenditure and with low costs. A very high degree of accuracy is possible from the selector through a rotational and highly adjustable rotation spindle.

Abstract: The invention relates to an atomic absorption spectrometer, comprising a measuring light path leading from at least one light source emitting line radiation corresponding to at least one element to be detected, through an atomization means for atomizing a sample containing the element to be detected, to a detection means, and a reference light path leading from each light source to the detection means. The invention is characterized in that a beam splitting means is provided such that a first component of the line radiation of each light source is guidable via the measuring light path and a second component of the line radiation of each light source is simultaneously guidable via the reference light path.

Abstract: The present invention refers to a spectrometer device comprising a monochromator means, a light-measuring means receiving light from said monochromator means, and a calibration means comprising a calibration light source. The present invention provides a new spectrometer device whose light-measuring means comprises a plurality of light-measuring elements in an array extending in the direction of dispersion of the monochromator means, and whose calibration means carries out, on the basis of a spectral light measurement with the aid of the calibration light source, an association between the light-measuring elements and the wavelengths of the spectral light which is adapted to be detected by the respective light-measuring elements. These measures substantially facilitate the calibration and especially the automatic execution of said calibration, if desired simultaneously with a spectra measurement, and they improve the accuracy of the calibration.
