Abstract
The analysis of lead in paints was previously used for the characterisation of pigments. In this way, the analysis is able to specify the century of the painting of a work of art. Recently this technique was also used to determine the toxicity of lead paints in building. This paper compared the result of several X-ray fluorescence spectrometer, either wave length/energy dispersion laboratory apparatus or X-ray microtube/radioactive source portable equipment's.

Résumé
L'analyse du plomb dans les peintures a jusqu'à présent été appliquée essentiellement pour caractériser les pigments lors de leur fabrication et pour identifier des rouvres d'art. Récemment cette technique est également utilisée pour déterminer la toxicité des peintures au plomb dans les bâtiments. Nous avons comparé les performances de plusieurs spectromètres de fluorescence X, soit de laboratoire à dispersion en longueur d'onde ou à dispersion en énergie (avec tube à rayons X), soit portable avec source radioactive ou tube à rayons X.

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.
  • If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
  • You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
  • You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
