Role of the BCR: good results can be obtainedFunded under: FP2-BCR 4
In the framework of the BCR-programme of the Commission of the European Communities many intercomparisons are being held to improve the quality of results of chemical analysis. Often a sequence of intercomparisons is set up in such a way that sources of error can be identified in various steps of the whole analytical procedure applied by a participant ("step-wise" approach). An intercomparison can also be used to measure the improvement achieved in such exercises. The results of such improvements demonstrate that participation in QA- and QC- schemes is worthwhile. Examples are chosen from different areas of environmental analysis, such as monitoring of organic vapours at the work place, traces of chlorinated biphenyls in fish, elements in coal and others. It is also shown that results better than predicted by the Horwitz-- equation can be obtained, if laboratories make a considerable effort to increase the quality of their performance.
