1. On-line Isotope Dilution Determination of Mercury Species by Solid-Phase Microextraction GC-ICPMS
William C Davis, Steven J Christopher, Stephen E Long, William R. Kelly
This preliminary technical note reports on the development of an on-line isotope dilution (ID) method that is applicable for the determination of inorganic and organic mercury species in marine samples. The method is demonstrated on NIST Standard Re ...
