Thermo Scientific Niton XL2 XRF Precious Metal Analyzer Repair
This is the Niton XL2 platform configured for precious metals: karat determination, separating solid gold from plating, and quantifying the alloying elements that change what an item is actually worth. The tolerance for error here is different from alloy sorting — a small drift in accuracy becomes a pricing error on every transaction, which is why detector and window condition matter more on this configuration than on any other XL2.
June Company’s certified technicians repair the Niton XL2 Precious Metal Analyzer for retail jewelers, pawn operators, refiners, precious metal buyers, and assay offices. We diagnose and repair at the board and component level, and every instrument is functionally tested against a known reference sample before it ships back.
Common Niton XL2 Precious Metal Analyzer problems we fix
- Punctured or clouded measurement window — worn quickly by constant contact with jewelry, and a direct cause of drifting karat readings.
- Detector resolution loss — the fault most likely to show up as karat values that no longer agree with a known sample.
- Gold-plating detection no longer flagging correctly — plated items reading as solid, which is the costliest failure mode on this instrument.
- X-ray tube output degradation — readings taking longer and becoming less repeatable.
- Small-spot collimation faults — readings not landing where the operator aimed on small components.
- F — a.
- T — o.
FAQs
My karat readings have drifted against a known sample — repairable? Yes. Drift of that kind normally traces to the window or the detector, and both are repairable.
Plated pieces are reading as solid gold. Is that the same fault? Not necessarily, but it is the one worth acting on quickly. We diagnose the plating-detection path specifically.
