Surface chemical analysis. Use of Total Reflection X-ray Fluorescence spectroscopy in biological and environmental analysis Ingestion-build-84997 The requirements of this standard1 Scope This Technical Specification provides a framework on the uses of Total Reflection X Ray Fluorescence (TXRF) spectroscopy for elemental qualitative and quantitative analysis of biological and environmental samples. It is meant to help technicians, biologist, doctors, environmental scientists, and environmental engineers to understand the possible uses of TXRF for elemental analysis by providing the guidelines for the characterization of
