EPMA-1720Shimadzu electron probe

An electron probe (EPMA) is an analytical device that uses an extremely fine electron beam to irradiate the surface of a sample to generate characteristic X-rays. The characteristic X-rays are then subjected to spectroscopic and intensity measurements to obtain the elemental composition of small regions and the concentration distribution of elements on the sample surface. Due to the non-destructive and high-precision analysis performed by Shimadzu electron probes, which can provide information that other instruments cannot provide, they are widely used in universities and national laboratories, gradually expanding from the initial field of metal and semiconductor materials to the analysis of particles, minerals, catalysts, and biological tissues. Given the superior analytical capabilities of electronic probes, the demand for high-end models in the market has been increasing year by year.

Features:

♦ Excellent spatial resolution

The highest level of secondary electron image resolution that can be achieved by an electron probe is 3nm (acceleration voltage 30kV), and the secondary electron resolution of No.1 under analysis conditions.

When the acceleration voltage is 10kV 20nm@10nA / 50nm@100nA / 150nm@1 μA）

♦ Analysis of ultra-high sensitivity for large beam current

Achieve a maximum beam current of 3.0 μ A (acceleration voltage 30kV). Can perform surface analysis of trace elements with ultra-high sensitivity. And there is no need to replace the objective lens aperture for the entire beam range.

♦ High performance X-ray spectrometer

Adhering to the advantageous 52.5 ° X-ray extraction angle of Shimadzu electron probe. Adopting a 4-inch Roland circular radius spectral crystal that balances high sensitivity and high resolution. It can be equipped with a 5-channel high-performance X-ray spectrometer simultaneously. The analysis performance is superior.

♦ All analysis operations are simple and easy to understand

Advanced operability where all operations can be performed with just one mouse. Pursuing a user-friendly interface that is easy to understand. Equipped with navigation mode, it automatically guides until a report is generated.
