Proficiency testing performance of Turkish laboratories on determination of relative composition of fatty acids in sunflower oil

Proficiency testing of laboratories in Turkey to compare and evaluate their performances on analysis of fatty acids in sunflower oil was performed. Analysis of the quality control test material allows the laboratory to compare the analytical results with other laboratories.In order to increase the quality of chemical analysis and awareness of metrology, TÜBİTAK UME have been organizing Proficiency Testing Schemes in the field of determination of fatty acids in sunflower oil since 2005. In this study, an overview of the proficiency test for the determination of fatty acids in sunflower oil in Turkey is presented.
