ESI - Model EDX6000D -XRF Gold Analyzer
XRF is a fast, precise & non-destructive tool for accurate analysis of materials & coating thickness. The XRF spectrometer precisely and swiftly determines the percentage by weight (or Karat) in a solid piece of jewellery, precious coins or any other piece of noble metal making use of EDXRF assay technique. It quickly and accurately determines the elemental concentrations of all Gold alloys, Platinum group metals & Silver alloys. The analysis of materials & coating thickness in non-destructive without any requirement for sample preparation, which reduce the analysis time of customer. The ESI XRF Gold Analyzer is an easy-to‑use, cost-effective method to obtain alloy chemistry and karat classification with one nondestructive and test. Additionally, an exclusive ESI XRF Gold Analyzer software feature helps identify gold-plated objects and sends an alert to the screen.

The X-ray fluorescence spectrometer consists of the following parts: X-ray generator (X-ray tube, high-voltage power supply), optics(analysis crystal, collimator and filters), counting and recording system ( Pulse radiation analyzer, calibration meter, timer, integrator, recorder). Different elements have characteristic X-ray spectra with different wavelengths, and the fluorescence intensity of each line has a certain relationship with the concentration of the element. Qualitative and quantitative analysis can be performed by measuring the wavelength and intensity of the characteristic X-ray line of the element to be measured.
