Electron Microscope Imaging Service—Kratos AXIS-165

Electron microscopes can excite electrons to form images that magnify micron and nanostructures up to 10 million times, providing amazing levels of fine magnification and allowing researchers to observe even individual atoms. CD BioSciences can provide innovative solutions for electron microscopy and microanalysis. We offer Kratos AXIS-165 instruments that allow customers to combine high-resolution imaging with physical, elemental, chemical and electrical analysis to obtain usable data from the widest range of samples.

Name of the Instrument/Platform

Kratos AXIS-165

Introduction

For XPS the instrument has a Monochromatic Al X-ray source and is fitted with a charge neutralization coil. Depth profiling can be done either by tilting the specimen (nondestructive) or using an argon ion gun (destructive). Imaging XPS is possible by using scan plates to raster the focal point of the analyzer over the specimen.
X-ray photoelectron spectroscopy is a surface-sensitive analytical technique that relies on the Photoelectric Effect discovered by Einstein (Nobel Prize 1921) . It is a semi-quantitative method for obtaining composition and chemical state information. Because it is a surface-sensitive technique and the photoelectrons generally have low kinetic energies, XPS experiments must be conducted in an ultrahigh vacuum (UHV) environment (10^-9 - 10^{-10 Torr).
X-rays of a fixed wavelength irradiate the specimen and the energies of photoelectrons generated are measured using a hemispherical analyzer. Given that the binding energy of each element's}

Summary

The Kratos AXIS-165 Surface Analysis System is a multi-technique instrument. Our instrument is equipped for X-ray Photon Spectroscopy (XPS-also known as ESCA (Electron Spectroscopy for Chemical Analysis)). This technique is surface sensitive (less than 8 nm for XPS) with a spatial resolution in X and Y of down to 30 µm.
