Coltide Drift Monitor for XRF

Better Analysis

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.

Dr Norrish has spent his career with Australian CSIRO developing innovative equipment and methods for analyzing soils and clays by x-ray fluorescence. He is recognized as an authority in this field and is a Fellow of the Australian Academy of Science.

Monitor Composition

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.
