Measuring precisely with only 40 ml of sample

BrulandIt is now possible to measure precisely manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), cadmium (Cd), and lead (Pb) concentrations in seawater using only 40 ml of sample.

All the cooking recipes and techniques are given in the recent detailed article of Dondra Biller and Kenneth Bruland in Marine Chemistry (Biller and Bruland, 2012). A work full of perspectives for trace metal measurements in the framework of GEOTRACES. Don’t miss it!
