Every year the Cooperation of International Traceability in Analytical Chemistry (CITAC) highlights remarkable papers which are particularly worthwhile to draw attention. In arbitrary sequence, the three award winning articles in the 2009 campaign are

Luca Callegaro, Francesca Pennecchi, Pier Giorgio Spazzini. Comparison of calibration curves using the Lp norm. Accred Qual Assur (2009) 14:587–592

Samuel Wunderli, Hanspeter Andres. Metrological Aspects of Glucose Measurements by Biosensors. Electroanalysis (2009) 21:1984–1991

Olaf Rienitz, Detlef Schiel, Bernd Güttler, Michael Koch, Ulrich Borchers. A Convenient and economic approach to achieve SI-traceable reference values to be used in drinking-water interlaboratory comparisons. Accred Qual Assur (2007) 12:615–622

The winning articles were disclosed by the CITAC Chair Ilya Kuselman during the V Metrochem conference in November 2009 in Sao Paulo, Brazil. Congratulations to all the authors!

For the competition in a given year, papers should be nominated with an abstract (in English) and a supporting letter from a CITAC member before 1 September. Then all CITAC members are informed and called upon to give their votes for the three most appropriate papers. The results are published on the CITAC website at http://www.citac.cc, in the CITAC News and Accreditation and Quality Assurance et al.

CITAC invites all colleagues from the metrology and analytical chemistry communities to support the nomination process by providing proposals to the CITAC members (listed on the website).
