4 The Processor Tensiometer performs the whole experiment automatically. The liquid is raised until it just touches the bottom of the porous sample. The Role of Interfacial Tension Measurement in the Oil Industry Carole Moules, Camtel Ltd Abstract This paper concentrates on the principles. A K100 Tensiometer (Kruss, USA) was used to measure surface tensions (γ/mN m −1) for binary mixtures with water using a roughened platinum plate-detachment method under atmospheric pressure. Before each measurement the plate was thoroughly cleaned and flame-dried, this allowed the removal of surface active contaminants to form a new.
Department of Composite Materials Equipment K-Alpha, Monochromated high-performance XPS spectrometer Thermo Scientific, UK 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).
