Wavelength Dispersive Spectrometry (WDS)

Zirconium Niobium

Zirconium Niobium

High temperature alloys contain various refractory elements for enhanced properties. Many of these elements will be in low concentrations so the X-ray peak contribution may be quite small. Low beam energy analyses cause additional difficulties by requiring the use of higher order X-ray lines containing many peaks, all of which can overlap with other elemental peaks. The EDS spectrum (green) of a Zr alloy shows only the expected asymmetry of the primary Zr-La peak but no distinct contribution of other elemental X-rays. The WDS spectrum (red), in contrast, shows a distinct contribution of a trace amount of Nb masked in the tail of the primary Zr-L X-rays.
