In the gold jewellery manufacturing, it is essential to know the exact composition of materials to ensure conformity with karat gold standards and to avoid "giving away" precious metals for which customer is not paying.

The X-Ray spectrometer allows the determination of gold in jewellery alloys with high accuracy and high precision. Also the other present precious and non-precious metal at higher concentrations can be determined as well. The presence of the latter elements influences slightly the grade of accuracy in determination of gold.

Energy dispersive X-Ray fluorescence technology (ED-XRF) provides one of the simplest, most accurate and most economic analytical methods for the determination of the chemical composition of many types of materials. It is non-destructive and reliable, requires very little sample preparation and is suitable for solid, liquid and powdered samples. It can be used for a wide range of elements, from Chlorine (17) to Uranium (92), and provides detection limits at the sub-ppm level.
 
Models:
Arrow ElvaX
ElvaX is a desktop energy-dispersive X-Ray fluorescence (EDXRF) analyzer which does not require liquid nitrogen cooling for storage and ElvaX is used for quantitative and qualitative analysis of the elemental, composition of metal alloys, liquids, food and biological samples, powder assays, as well as samples deposited on surfaces or filters, in the element range from Cl (Z=17) to U (Z=92) in a wide range of element concentrations. The accuracy of determining concentrations is better than 0.3% for metal alloys. Analyzer's detecting limit is better than 1 ppm for most elements in light matrix.
