The set of  four glass disks is used in the analysis of cements, rocks, silicates, ashes etc.  These disks were carefully selected to provide wide calibration ranges of the most common elements. The disks are used as  'MONITORS'  for  the elimination of drift  in the slope and intercept of calibration graphs. Because they are made from glass, they offer long term stability under the X-ray beam and they are resistant to moisture. The disk surface is polished and can be easily cleaned.
