Key Challenges in Internal Quality Control (2012)

The Eurachem Education and Training Working Group organised an international workshop on internal quality control in Berlin on Wednesday 10 to Thursday 11 October 2012. The event was hosted by the German member of Eurachem, EUROLAB Germany. The workshop covered analytical results from a range of sectors and disciplines including chemical analysis, testing, laboratory medicine and microbiology. The main focus was on internal quality control performed in the laboratory for the continuous monitoring of operations and results of measurements, in order to decide whether results are reliable enough to be released. qcpic80
The workshop included invited lectures, short communications, posters and break-out sessions.
A training course on internal quality control was held at the same venue the day before the workshop, Tuesday 9 October.
