Presentation of the lab

The USRAVE works mainly on the plant. It is capable of preparing and of analyzing all the parts of the plant (fruits, stalks, roots, leaves, needles, wood, bark, cells, flours), and it for all the types of plants (trees, cereal, grasses, truck-farming plants).

Analyses realized in the USRAVE concern the essential major elements in the growth of plants (nitrogen, phosphor, potassium), trace elements (iron, copper) but also elements in metallic tracks having a direct influence on the environment or the health (cadmium, chromium, lead, mercury, nickel).

Being in the service of the researchers and participating in the production of scientific knowledge, the USRAVE has the obligation to supply reliable and strong results of analysis. So that the unit made a commitment from 1992 in an approach of quality assurance. The investment:

  • Material (Equipment): metrological controls, software of management of samples (LIMS),

  • Human being: training(formation), implication,

  • Technique: production of sample of control, validation of the methods, the scientist: developed successful and innovative methods

led to the recognition of its technical competence by the COFRAC (French committee of accreditation) on the program 99-3. (Initial Accreditation 03/2007, extensions 04/2008 and 07/2009 and 11/2011). Carried by the accreditation is available for consultation at the following address: http: // www.cofrac.fr or on our site. USRAVE develops new methods of analysis according to several axes such as:
  • Taken care by very low mass of samples (e.g. development of the coupling ETV-ICP-AES)

  • Quantification of very low concentrations (e.g. analysis of the platinum, paladium and rhodium by ICP-MS)
