Visit Supplier
Sourced in United Kingdom

The Thermo K-Alpha spectrometer is a versatile X-ray photoelectron spectroscopy (XPS) instrument designed for surface analysis. It provides high-resolution, quantitative elemental and chemical state information about the surface of a wide range of materials. The spectrometer utilizes a monochromatic Al Kα X-ray source and a high-performance electron energy analyzer to deliver precise data about the composition and chemistry of sample surfaces.

X-ray Photoelectron Spectroscopy of Dried Samples

Check if the same lab product or an alternative is used in the 5 most similar protocols
Surface compositions and chemical states were obtained after drying the samples at 120°C for 1 h and conducting X-ray photoelectron spectroscopy (XPS) using a Thermo K Alpha + spectrometer (Thermo Scientific) operating at around 10−8 to 10−9 Torr with a Al Kα radiation source (1,486.7 eV). High resolution spectra were collected for cobalt (Co 2p) and silica (Si 2p) to assess the oxidation states with the peaks normalised to the carbon peak (285.0 eV).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
