XRF Spectrometer thus far restricted only to the
Research Labs is the most scientific approach for the
elemental analysis which has found a new market segment
in the Gold Jewellery Industry for the most accurate and
reliable gold purity checking
Traditional Gold purity testing methods such as fire
assay and chemical analysis are time consuming,
cumbersome and destructive. XRF testing is relatively
simple, fast, reliable, inexpensive, no sample
preparation required and most of all is non –
destructive.
Energy Dispersive X-ray Fluorescence Spectrometer is used to detect and analyze noble metals like
Gold( Au), Silver(Ag), Platinum (Pt), Palladium (Pd),
Rhodium (Rh), Ruthenium(Ru), Copper (Cu), Zinc(Zn),
Nickel (Ni), Cadmium( Cd), Indium (In) in the Jewellery
Industry.
Energy Dispersive X-ray Fluorescence (EDXRF) technique
relies on the detector and the detection circuit
capability to resolve spectral peaks due to different
energy X-Rays emitted when a primary X-Ray beam strikes
a metal alloy corresponding to different elements in the
sample, intensity of the spectrum radiation proportional
to the concentration of element. The spectrum then
processed through the powerful computer software which
calculates and reports the various elements & their
composition in the sample.
XRF Gold Purity Tester consists of X-Ray tube, high
voltage power supply for X-Ray source, X-Ray tube
filters, gas proportional counter detector, processing
electronics and system interface & an external computer.
A camera is incorporated in the system to view the
sample on the computer screen.
XRF is a reference technique, hence standards are
required for quantitative results. Standards are
analyzed, spectral intensities generated are used to
obtain a intensity v/s concentration plot for
calibration. This calibration is used to evaluate the
spectral intensities of unknown samples.
