Laboratory Trace element analysis of seawater and phytoplankton. Trace elements (e.g. Fe, Mn, Co, Cu, Zn, Mo) in seawater strongly influence the growth of phytoplankton. To understand the cycle of trace elements [...] elements as well as the influence of trace elements on phytoplankton growth, the concentration of the mentioned elements in seawater and phytoplankton can be analyzed via the coupling of a SeaFast system to [...] Trace element analysis of phytoplankton cells. Using a high resolution ICP-MS of NuInstruments (figure 4D), trace metal concentrations (Fe, Co, Zn, Cd, Mn, Mo, Cu) of phytoplankton cells can be quantified
