This paper proposes the standardization of total reflection X-ray fluorescence (TXRF) analysis for environmental and biological samples. The importance of TXRF in environmental and biological analysis is now well established and it is continuously growing. However in these fields there are not standardized methods reported by the International Standard Organization (ISO). For this reason, the international collaboration for the development of new standard procedures and methods for TXRF analysis is required. Indeed, a project for “Interlaboratory comparison of TXRF spectroscopy for environmental analysis” was set up in the frame of the Versailles Project on Advanced Materials and Standards, with the aim of developing a new ISO standard for TXRF devoted to environmental and biological analysis.
