European Virtual Institute for Speciation Analysis for Improvement of health, food, industry and environment (EVISA). 01/04/2003 - 31/03/2006

Abstract

The goal of the European Virtual Institute for Speciation Measurements (EVISA) is to develop a highly interactive and innovative network operating to the advantage of all members of the Virtual Institute, i.e. individual industries (food, toys, pharmaceutical, cosmetics, waste water treatment plants, water supply companies, chemical industry, etc.), researchers, regulatory bodies, commercial and governmental laboratories. EVISA will summarise and disseminate in the most appropriate manner the existing knowledge on metal species determination from the academic world, interact on a daily basis with the industrial sectors to act on a consulting basis to provide the most appropriate solutions to questions and management of the questions raised. The aim of the proposed Virtual Institute is hence to give the industry access to a wide array of expertise concerning speciation measurements by bringing together all European capabilities in the sector.
