Analysis of tarnish-resistant silver alloys
X-ray fluorescence analysis of silver alloys with additions (Ga, Ge, Pd, Sn, In) that reduce tarnishing, with emphasis on standard-free measurement.
Measurement of gold coatings in the watch industry
Measuring gold plating on stainless-steel watches by beta backscatter (MMS PC2): X-ray fluorescence reaches only about 10 µm, the beta method up to 35 µm.

Determination of the silver content of silver-plated or blanched silver alloys
Ordinary XRF analysis shows too high a silver content because of the surface layer; the note describes a method that separates silver-layer thickness from the fineness of the base material.
Fast, reliable gold analysis for the gold-buying industry with X-ray fluorescence
Gold buyers need to value an item in minutes: how an XRF instrument gives purity quickly and simply, with hardly any calibration.
