8th International Workshop on Proficiency Testing (2014)
The 8th International Workshop - Proficiency Testing in Analytical Chemistry, Microbiology and Laboratory Medicine was held in Berlin, Germany during October 2014, organized by the Eurachem Proficiency Testing Working Group in association with EQALM and CITAC. This international PT workshop, building on the success of previous workshops, enabled 245 delegates from sixty-four countries to come together to discuss a wide range of key issues across the three disciplines of analytical chemistry, microbiology and laboratory medicine. The diversity of delegate backgrounds, which included PT/EQA providers, participants in PT/EQA schemes, end users of PT/EQA results such as accreditation bodies and regulatory authorities, national measurement institutes, laboratory associations, universities and independent consultants, coupled with their international spread, ensured a truly global perspective.
Available presentations and posters are listed below.
Additional details are currently available on the workshop website, www.eurachempt2014.de.
