WebXPS is used for the analysis of solid surfaces, thin films, and interfaces. The technique is considered to be standard-less, requiring no external calibration to obtain quantified results. It also requires little or no sample preparation. The number of application areas in which XPS is used is extensive, encompassing both WebXPS without compromise The Nexsa G2 System has a newly designed X-ray source, efficient electron optics, and fast signal detection to deliver excellent XPS sensitivity and resolution. The X-ray spot size, which defines the analysis area, can be varied in five-micron steps from 10 μm to 400 μm. This means that the analysis c moran zapatos

WebAug 21, 2024 · How XPS works. X-rays (photons) are shot onto a sample, and when electrons in the sample absorb enough energy, they are ejected from the sample with a certain kinetic energy. The energy of those ejected electrons is analyzed by a detector and a plot of these energies and relative numbers of electrons is produced. WebThe Thermo Scientific Nexsa Surface Analysis System is the newest XPS product from Thermo Fisher Scientific. At its heart, Nexsa is a high performance XPS instrument. It has a brand-new X-ray monochromator which has unparalleled sensitivity for large area analysis, but can operate at smaller X-ray spot size to enable small feature analysis as ...
