The Barnhart pulse pile‐up and dead time correction method is used by a number of manufacturers of energy‐dispersive x‐ray analysers. This method may provide inadequate correction at moderately high count rates and/or in the presence of low‐energy x‐ray peaks. A correction scheme is proposed to overcome these difficulties and its effectiveness is illustrated by the analysis of several homogeneous mineral samples of well established composition.
