Drift Monitors

XRF Drift Monitors

Because of its efficiency, fusion is often the method of choice for preparing a wide range of samples for analysis by x-ray fluorescence (XRF). To maintain accurate and consistent results, it is prudent to use Drift Monitors for correction of ageing x-ray tubes and sample preparation variances.

Based upon years of experience Dr Keith Norrish developed Coltide drift correction monitors to ensure ongoing data collected via XRF spectrographic sources was correlated and relative to the sample composition and source.

Product Description

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.
