Many trace metals are essential micronutrients for phytoplankton, and despite their low concentrations in seawater, trace metals can have large impacts on biological processes. Also due to their low concentrations, the measurement of trace metal concentrations requires precise analytical techniques. One common method utilizes expensive instrumentation that we do not have at HSU. In this research project, we adapted published methods to use the Flame Atomic Absorption Spectrometer (Flame AA), an instrument in the HSU Chemistry Department. Results show successful adaptation of the method for zinc and manganese. Current work streamlines the method to allow for eight-fold faster sample preparation.
