Electron Microscope

The M&P Lab is equipped with a sophisticated state-of-the-art scanning electron microscope (SEM) and an electron microprobe. The SEM is capable of operating in conventional high vacuum or variable pressure vacuum, which permits examination of non-metallic and non-conductive materials without coating or sample preparation. Maximum sample dimension is greater than 250 mm (10 inches) with maximum mass of 4.5 kg (10 pounds). The SEM is equipped with light element EDS (energy-dispersive spectrometry) to obtain qualitative information about the chemical characteristics of a sample and WDS (wavelength dispersive spectrometry) to obtain positive identification of trace or overlapping elemental X-ray lines and precise quantitative analysis. The electron microprobe is a scanning electron microscope (SEM) that has been optimized for flexibility and accuracy in elemental analysis and is equipped with two fixed and four scanning WDS as well as high throughput EDS for qualitative and quantitative standard-based chemical analysis. The high probe current enables rapid collection of excellent X-ray maps. Seven wavelength spectrometers determine a material's elemental composition on a microscopic scale. The M&P Lab has been providing electron microprobe analysis for nearly 40 years, and our latest microprobe was recently upgraded with state of the art hardware and software.
