Validation of a Portable Flow Injection-Chemiluminescence (FI-CL) Method for the Determination of Dissolved Iron in Atlantic Open Ocean and Shelf Waters by Comparison with Isotope Dilution-Inductively Coupled Plasma Mass Spectrometry (ID-ICPMS)
A blind intercomparison exercise was carried out to validate a well-documented, portable flow injection chemiluminescence (FI-CL) method for the determination of iron in seawater. This was done by the analysis of a variety of filtered Atlantic Ocean samples using FI-CL data and a potential primary m...
