The monitors are manufactured as stable fortified glass discs that are used to correct for day to day drift in the x-ray output. It is intensities that matter.
These are not intended as primary standards but are normally used for XRF calibration drift. Each type of monitor has element compositions that are appropriate for the mineral type. Trace element intensities are adjusted to be well above background.
The XRF Drift Monitors discs are 40mm and 32mm diameter. They have a thickness of approximately 4mm and are polished flat so that they can be mounted precisely and are easily cleaned.
