Handheld & Benchtop XRF Spectrometers
GoldPaid utilizes Thermo Scientific Niton XRF analyzers equipped with silicon drift detectors (SDD) capable of resolving elemental concentrations down to 0.01% for Gold (Au), Silver (Ag), Platinum (Pt), Palladium (Pd), Copper (Cu), and Zinc (Zn).
Daily Calibration & Standard Reference Materials
Analyzers undergo daily standardization using certified alloy reference samples prior to testing customer parcels, ensuring 100% assay repeatability.
Common questions
Does XRF testing leave any residue or marks on jewellery?
None whatsoever. XRF spectrometry measures surface fluorescence excited by low-energy X-rays without scratching, filing or acid contact.
