WG2: Metrology and standardization

Leaders: D. Eichert [IT] & T. Hase [UK]

The main goal of the WG2 “Metrology and Standardization”, is to help in establishing TXRF as a reference/ certified technique for reliable elemental analysis, both for screening and accurate quantitative determination.
This will be tackled via the following objectives and activitie:


  • To describe TXRF workflow and its domains of applicability;
  • To validate protocols for sample preparation, measurement conditions and TXRF analysis by means of interlaboratory studies and comparison with other independent techniques;
  • To ensure the quality and validity of quantification procedures, via monitoring the repeatability, reproducibility and accuracy of the proposed protocols (good laboratory and quality management practices);
  • To enhance technical standards, standard operating procedures, norms (pre-normative activities) and EC regulations and to provide input to standardization bodies and metrology institutes, also within the frame of ISO;


  • Development of a common definition of the state of the art for TXRF;
  • Review and update of TXRF related standardization and exploitation activities;
  • Review and definition of the availability of standards and qualified applications for e.g. quality control equipment and analytical services to support the competitiveness of related- industries;
  • Survey and questionnaire to stakeholders to outline standardization needs;
  • Joining the separate approaches of chemical and physical traceability needed to propose TXRF as a primary chemical method;
  • Defining and scoping documents for inter-laboratories studies;
  • Coordination of inter-laboratory studies and joint experimentation at the European and Worldwide level of different samples, defined as critical by current regulation bodies;
  • Quality assurance, robustness and traceability of analyses results;
  • Proposing new standards to be developed, and update on the existing standards;
  • Ensuring bridges with liaison bodies such as standardization entities (ISO, CEN, and corresponding National standardization bodies), regulation entities (European Commission), pre-normative research networks (VAMAS), Consultative Committee for Amount of Substance (CCQM), metrology institutes and stakeholders
  • Connecting and strengthening collaborations among European and International scientists and experts with different background to create an accessible pool of competences consortia for researchers;
  • Developing a realistic TXRF road map by identification of the needs and barriers related to cost and performances;
  • Engaging industrial, metrology institute stakeholders;
  • Organization of dissemination events such as Conferences and training Schools, sessions and workshops dedicated to metrology and standardization.
