Abstract

International Schools of Ion Chromatography are well-accepted annual meetings among users of ion chromatography in Slovenia and Croatia. Special attention is also given to some features of metrology e.g. tracebility and uncertainty. Within schools, proficiency tests are organized, with the aim of checking the performance of participating laboratories as well as of testing different analytical approaches suitable for certain types of samples. The procedure for preparation of a laboratory reference solution (Cl- and Br-) using primary techniques with direct traceability to SI units is also shown.
