Contact angle measurement machine

Contact Angle Measurement - Per Hour Charge

£120.00

Description

Per Hour Charge for use of the Contact Angle measurement equipment.

LMCC has a DataPhysics OCA 20 which provides the capability to determine contact angle measurements, it can calculate the surface and interfacial tension of liquids by means of a pendant drop method or for high-viscous materials by use of a Lamella method. The main advantage being its relative ease and quickness of operation.

Contact angle measurements are useful for wettability and surface free energy estimations on a range of solid surfaces. These studies are important to a number of industries including painting, printing, adhesive bonding, polymer processing and manufacturing. A commonly used method is the sessile drop technique to study wettability. In addition, advanced and receded contact angles can be measured and the difference between these, the hysteresis, can give an indication of surface chemical heterogeneity and roughness.

X-ray Photoelectron Spectrometer (XPS) system

X-Ray Photoelectron Spectroscopy - XPS, Per Hour Charge

£150.00

Description

Per Hour Charge for use of the X-Ray Photoelectron Spectroscopy.

LMCC has a fully integrated, monochromated small-spot X-ray Photoelectron Spectrometer (XPS) system. This system has state-of-the-art performance, increased ease of use with multi-user environment and fully automated workflow from sample entry to report generation.

X-Ray Photoelectron Spectroscopy (XPS) or often referred to in general terms as Electron Spectroscopy for Chemical Analysis (ESCA). The system can be used in the element identification of samples and can also provide information about an element's chemical environment or oxidation state, it can be used for almost any solid material, including insulators.
