Long-term Stable Drift Monitors (Control Samples) for Drift Correction

Like most analytical instruments, X-Ray fluorescence spectrometers show changes in their analytical performance over time. The X-Ray tube loses intensity and the detector loses sensitivity after using them for a while. This negatively affects calibrations installed on the machine.


To use an existing calibration over a long time, the change in sensitivity for an element must be detected by a drift monitor and then used to correct this "drift". Such samples are called drift monitors, monitor samples, reference samples or monitor standards.


Drift monitors have the special property of not showing any change in element composition over a long period of time.


That´s why FLUXANA calibrations, installed by us in many customer laboratories, contain a special selection of drift monitors to guarantee an excellent long-term stability.  These monitor samples were designed in our own glass production to assure highest quality.
