Wavelength Dispersive Spectroscopy (WDS) System available for use

Amy Morgan

The Wavelength Dispersive Spectroscopy (WDS) System is now open and available for use and training. This instrument complements Energy-dispersive Spectroscopy (EDS) by offering excellent peak separation, accurate trace element analysis, and optimised element detection for low and high energy X-rays to provide "Microprobe Accuracy on an SEM".

Features of the WDS include accurate quantitative analysis below 500pppm and accurate quantitative analysis below 500pppm along with easily and unambiguously determines the distribution of all elements in a sample even where peaks overlap. The WDS also has up to 100 times more sensitive than an EDS system for trace element detection and the most accurate elemental analysis available for SEM.

A workshop on the WDS will be held on October 26, 2016. More details to come.

Contact Eric Miller (eric-miller@northwestern.edu) for training and more information.
