Niton XRF Analysers


Don’t Waste a Precious Minute


Following the release of recommended guidelines for use of XRF Analysers for the analysis of precious metals by the Jewellery Council of South Africa, we would like to highlight further key points in the analysis process, such as radiation safety and the need for annual calibration of your XRF.

What is XRF

XRF is a non-destructive analytical technique used to determine the elemental composition of materials. XRF analyzers determine the chemistry of a sample by measuring the fluorescent x-rays emitted from a sample when it is excited by a primary x-ray source. Each of the elements present in a sample produces a set of characteristic fluorescent x-rays (“a fingerprint”) that is unique for that specific element.

Radiation safety when using XRF

1. Know where the beam is!

2. Provide training to operators.

3. Never aim at yourself or others.

4. Never hold samples during analysis.

5. Handle and Use with Respect.

Annual Calibration of your XRF is necessary

Calibration is the process where you confirm that your measurements are true by measuring against a standard. Calibration is usually done on the instrument before it gets shipped out the manufacturer’s door. And although portable XRF analyzers are usually quite rugged, especially since they are sometimes used in harsh environments, equipment degrades over time and should be recalibrated periodically.

Generally, recalibrations should be done annually to ensure that measurements are accurate within the specification limits that led you to select the instrument in the first place. However, recalibrations should only be done by the manufacturer’s qualified technicians.

Never attempt to open up the instrument as you can damage or compromise the technology.

Exceptionally Fast. Simple and Easy to Use.
