K-Alpha, Monochromated high-performance XPS spectrometer

Thermo Scientific, UK

XPS In X-ray Photoelectron Spectroscopy (XPS) we are concerned with a special form of photoemission, i.e., the ejection of an electron from a core level by an X-ray photon of energy hv. The energy of the emitted photoelectrons is then analysed by the electron spectrometer and the data presented as a graph of intensity (usually expressed as counts or counts/s) versus electron energy - the Xray induced photoelectron spectrum. XPS is a surface sensitive technique, since the depth from which information can be derived is a few nanometers (2-10 nm). In our laboratory we are performing surface analysis of solid samples (plates, films, powders) of the size up to 60 x 60 x 20 mm (width x length x height).

The nanofiber technology of present interest focuses on the electrospinning technique, which conveniently allows the preparation of fibrous materials with very fine diameters ranging from submicron to several nanometres, through an electrically charged jet of polymer solutions. The basic setup consists of syringe with polymeric solution with a metallic needle tip. On the needle is connected high voltage supply. If the electrostatic force was able to overcome the surface tensions of the sample solution, the fibers are created. These are collected on the grounded metal collector, where is so called non-woven mat established.


Plasma generator Low Cost System Zepto

Diener electronic GmbH

Plasma generator Low Cost System Zepto

Plasma technology can be used on different materials such as glass, metal, plastics, textiles and ceramics and for different purposes such as surface cleaning, surface activation, surface etching and surface deposition – plasmapolymerization.
Organic remains are chemically transformed during the plasma process. The surface is subjected to a fine cleaning. Nearly all materials can be cleaned with an oxygen plasma.
Plasma activation is used to transform non-polar surfaces such as plastics (PDMS, PE, PP, ...) into adhesive surfaces. The surface energy is increased without damaging the material’s properties.
