X-RAY SPECTROMETER COMPRISING A PLURALITY OF FIXED MEASURING CHANNELS

摘要

An X-ray spectrometer comprising at least one fixed measuring channel can be used to measure a spectral line and possibly a limited vicinity thereof. If this spectrometer is to be arranged for the measurement of a plurality of spectral lines, in accordance with the invention it can be provided with a plurality of analyzer crystals which are associated with one, fixed detector only, and with a changer device for realizing each time a desired configuration in which one of the analyzer crystals is situated in a fixed location, associated with the relevant analyzer crystal in the beam path between the sample and said detector during the measurement. It is then no longer necessary to mount for each spectral line a separate measuring channel (i.e. an analyzer crystal and an associated detector) in a reserved special location on the housing of the spectrometer, so that a substantial cost saving is achieved.
