A NON-DESTRUCTIVE X-RAY FLUORESCENCE METHOD FOR ANALYSIS OF METAL ALLOY WIRE SAMPLES

Although quantitative analysis of metal alloys is typically accomplished by wet-chemical techniques, complete dissolution of some metal alloys can be difficult. Here, we report an alternative non-destructive energy-dispersive x-ray fluorescence (EDXRF) method for determination of nickel, gold, copper, and silver in metal alloy wires. Sample preparation is simple and consists of mounting wires as a single strand in machined polyethylene sample cups. Wires are analyzed in two symmetrical positions nearly parallel to the x-ray beam, thereby improving the external reproducibility of the analysis. Ideally, standards and samples are matched in terms of chemical composition and diameter. For 50 mil copper-silver wire, four certified reference wires consisting of various copper-silver compositions and matching the unknown diameter were used. However, we also investigated standards of different elemental composition and thickness. For analysis of 25 mil nickel-gold wires, 20 mil NIST standard wires consisting of copper-gold were applied for standardization and compared with certified 25 mil nickel-gold standards. Variations in wire diameter were corrected using an infinite thickness approximation, and nickel intensities were calculated from the copper intensities using a fundamental parameters calculation. The standard curves obtained from both approaches are similar, indicating that wires of varying thickness and composition can be applied as standards. Analysis of copper-silver and nickel-copper wire “unknowns” agrees with certified values to better than 0.3 wt %. We conclude that this rapid, non-destructive method could be a useful alternative to wet-chemical methods for many applications.

The Lux Group Apple Watch Diamond Edition

The Lux Apple Watch Diamond Edition is supplied by setting jewels, which endows the Lux Apple Watch with its unique qualities, playing with a myriad of precious stones of extraordinarily varied hues, dimensions and shapes. To achieve perfect uniformity of tone, three times more gems must be cut than are actually necessary for the bezel of the watch. Each one is individually placed according to its destined position in this piece of illuminated marquetry.
