Forschungsdesign und empirische Analyser enrichment of analytes due to the fact that majority of analytical techniques are not sensitive enough for direct determination of trace compounds. On the other hand, sample preparation is considered as crucial part of whole analytical procedures, in particular in samples characterized by complexGranular 发表于 2025-3-28 23:21:51

Terrorismus im Zeitalter der Globalisierung,lytical chemistry offers dozens of analytical procedures, based on different sample preparation and final determination techniques that are used for the determination of a given analyte in a given matrix. For such complex decision-making processes, multi-criteria decision analysis tools are appliedHarass 发表于 2025-3-30 06:56:45
