| Abstract: | Summary A method for the determination of elements in liquids using inductively coupled plasma mass spectrometry (ICP-MS) is described. The different possibilities and problems together with instrumental parameters are reviewed. After the dissolution step samples are analyzed directly without any preconcentration. Detection limits for 53 elements have been tested and are found to be less than 0.1 ng/ml. Monoisotopic elements can be detected at levels less than 0.05 ng/ml. Interference problems have been studied and hints are given to predict molecular species using algorithm implemented in software packages. The application to trace element analysis in the geological field is demonstrated with a basalt reference sample to verify figures of merit for this method. Accuracy is checked with a NBS SRM steel sample.
