X-ray photoelectron spectroscopy (XPS) is a surface-sensitive quantitative spectroscopic technique that measures the very topmost 50-60 atoms, 0.01 um, 5-10 nm of any surface. It belongs to the family of photoemission spectroscopies in which electron population spectra are obtained by irradiating a material with a beam of X-rays.

实验信息 为了更快的采集，通常在采集 C1s 区时，将范围扩大到 305eV，以采集 K2p 区。 XPS 谱图解读 K2p 峰具有明显的自旋轨道分裂峰（Δ 氯化物 =2.8eV）。 较弱的 K2p 峰很容易与芳香族化合物中的 C1s (CF 2) 峰或 C1s 卫星结构混淆。

The Thermo Scientific K-Alpha X-ray Photoelectron Spectrometer (XPS) System brings a new approach to surface analysis. Focused on delivering high-quality results using a streamlined workflow, the K-Alpha XPS System makes XPS operation simple and intuitive, with no sacrifice in terms of performance or capabilities.

Potassium X-ray photoelectron spectra, potassium electron configuration, and other elemental information. Charge referenced to adventitious C1s peak at 284.8eV. It is often quicker to acquire C1s region and extend range to 305eV to capture the K2p region. K2p peak has clearly spaced spin-orbit components (Δ chloride =2.8eV).

KXPS (1010 AM) is a radio station licensed to Thousand Palms, California, United States. It previously broadcast a sports radio format. On May 26, 2022, KXPS began promoting a "change is coming" on June 1, 2022. [2] . On that day, the station went silent and its sports format moved to KJJZ - HD3 as "102.7 The Fanatic". [2] .

The Thermo Scientific™ K-Alpha™ X-ray Photoelectron Spectrometer (XPS) System is a fully integrated, monochromated small-spot XPS system with depth profiling capabilities.

X-ray photoelectron spectroscopy (XPS or ESCA) curve fitting procedures, reference materials and useful notes are listed here to provide a starting point for the consistent interpretation of XPS spectra.

The Thermo K-Alpha XPS uses a focused beam of x-rays to eject electrons from the near-surface region of a sample in a vacuum. The energies of those electrons are characteristic of the elements from which they came and the specific chemical bonds that involve those elements.
