Oxford Authentication Ltd was formed in 1997. Since its formation, we have performed over 18,000 tests. Clients come from all parts of the world, and include major museums, auction houses, dealers and collectors. The company is international, with representatives in Hong Kong, the USA and Europe, as well as in countries such as Australia, New Zealand, Israel and South Africa.

Our thermoluminescence (TL) laboratory has state-of-the-art equipment. There are three fully automated, computer-operated Riso Minsys TL readers that are constantly updated, and we have twelve Elsec alpha counters. The alpha and beta sources, integrated in the TL readers, have been fully calibrated in collaboration with workers in Australia and Munich, and the dose-rate adjusted each year. Since the TL signal can be very faint in some samples, the photomultiplier tubes in the TL readers are specially selected to be most effective.

Care in sample preparation is absolutely crucial. Our preparation facilities include two Buehler low speed diamond saws for cutting porcelain, a range of drilling equipment, plus a high specification fume cupboard, drying oven and centrifuge for the preparation of samples

Oxford Authentication Ltd is the only TL testing laboratory in the world working to full international quality assurance standards, with Lloyds Quality Assurance, ISO 2000.
