Detailed Applications for WDS

Wavelength Dispersive Spectroscopy (WDS) lends itself to applications requiring quantitative compositional results from solid samples, particularly where concentrations of minor and trace elements need to be accurately determined. Application examples exist in a wide range of sectors, including metallurgy, geology, electronics, semiconductors, forensics, and energy generation and storage. Combining WDS with EDS analysis, through AZtecWave, provides a versatile system for non-destructive, compositional analysis in the SEM.
