Abstract
In an X-ray analysis apparatus, a pulse amplitude shift correction circuit is provided for producing correction signals which are a measure of pulse amplitude shifts and which are in response to the pulse amplitude shifts. This circuit provides automatic correction of pulse amplitude shifts so that the pulse amplifier of the device is controlled.
