Direct determination of 10 trace metals in 50 mL samples of coastal seawater using desolvating micronebulization sector field ICP-MS†

Understanding the trace metal marine geochemistry of temporally variable coastal systems requires intensive sampling programs with attendant analytical burdens. Most established techniques for multi-element trace metal determinations are slow, require a skilled chemist, and are not easily automated. Advances in sample introduction systems and ICP-MS instrumentation now provide marine chemists w...

Simultaneous Spectrophotometric Determination of Vanadium(V) and Iron(III) in Micellar Medium by H-Point Standard Addition Method

H-Point Standard Addition Method (HPSAM) was applied for the simultaneous determination of V(V) and Fe(III). The method is based on the complex formation of V(V) and Fe(III) with chromazurol S (CAS) in acidic media and in the presence of cetyltrimethylammonium bromide (CTAB) as a micellizing agent. Acidic media and the presence of a micellar system improve selectivity and sensitivity. Fe (I...

Direct Analysis of Seawater using the 7800 ICP-MS with HMI for Aerosol Dilution

Trace elements determination in seawater by ICP-MS with on-line pre-concentration on a Chelex-100 column using a ‘standard’ instrument setup.

Trace element determination in seawater is analytically challenging due to the typically very low concentrations of the trace elements and the potential interference of the salt matrix. A common way to address the challenge is to pre-concentrate the trace elements on a chelating resin, then rinse the matrix elements from the resin and subsequently elute and detect the trace elements using induc...
