This should in principle permit the reliable and extremely precise analysis of trace compounds mainly trace elements, at levels down to the lowest natural concentrations. However, the frequently observed very high discrepancies between the analyt ical results of different laboratories as well as the deviations from true values are, regrettably, still common in analytical practice. Basic methodological errors at the determination step can usually be minimized or even avoided by carefully per formed quality control measures - e. g. by interlaboratory comparisons and the proper use of certified reference materials. The most severe and often under estimated error sources, however, are those connected with the whole and often extremely complex sampling process, and also to a lesser extent, with sample pre paration prior to analysis. Thus, for these initial steps of an analytical procedure particular experience is needed, as well as a detailed knowledge of the interrela tions between these steps, which always have to be applied with the utmos | | 出版日期 | Book 1997 | | 关键词 | Chemische Analyse; Probenaufschluß; Probennahme; chemical analysis; quality assurance; sample preparation | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-642-60632-8 | | isbn_softcover | 978-3-642-64486-3 | | isbn_ebook | 978-3-642-60632-8 | | copyright | Springer-Verlag Berlin Heidelberg 1997 |
