PRODUCTS Gas purification without interruption Aeronex has launched the Infinity gas purification system, which can supply large volumes of high purity gas for use in the high specification production of blue, green and white LEDs. Ammonia, hydrogen and inert gases can be handled by the system, with flow rates of up to 3000 slm. The Infinity system is designed with two purifier beds to provide a continuous supply of pure gas and in situ regeneration. While one bed is on-line, the other is automatically
regenerating. The inorganic media in the purifier beds operates at room temperature and handles high flows at very low pressure - one of the requirements for next generation MOCVD production equipment. www.aeroilex.com

Searching for surface coatings?
These modules give a choice or combination of indentation, scanning and impact testing to create an analysis system that can be tailored to a wide range of applications. Also available from LOT Oriel is Thermal Wave's Thermoscope, which offers fast, non-contact, subsurface imaging in a small lightweight unit. The Thermoscope combines a flash lamp system with a thermal imaging camera and analysis software to simplify and automate inspection, of polymer voids and nonuniformities for example.
The World Surface Coatings Abstracts (WSCA) CD-ROM will now be published on a monthly basis, from June 2001 onwards. The CD-ROM, which holds almost 250 000 records, can be used in a stand-alone format, on a company intranet, or via the Internet. The searchable data contained on the CD includes journal articles and patents covering raw materials through to coating types, applications to properties.
