Abstract

The invention relates to an arrangement and method for multielement analyse of chemical elements in which light cables are used to transmit spectral lines or bands produced by an optical dispersion means from a sample material radiation to an array of photodetectors. The light cable end-portions are inserted as many as required for a definite analyzing program into holes of a plug-in unit and are associated via a mask to definite photodetectors. The plug-in unit is displaceable relative to the mask so that the spectral informations from definite light cables associated to definite spectral lines or bands are evaluated in groups which require similar or equal excitation conditions. The latter are adjustable by respective means.
