ABSTRACT

The direct elemental analysis of saline matrices such as brines and seawater poses significant challenges due to high salt content, which can compromise signal stability, cause ionization interferences, and reduce the lifespan of sample introduction components. This study demonstrates the capabilities of the newly launched Analytik Jena’s PlasmaQuant 9200 ICP-OES system, a space-saving powerhouse, for the accurate and stable analysis of undiluted saline samples, specifically a 35 g/L NaCl matrix. Utilizing its high-resolution optical system and robust plasma performance, the instrument achieved matrix-specific detection limits in the sub-ppb range for trace elements, while also quantifying major components in a single run. We show that lowest argon plasma gas flow of 8.5 L/min is achieved without affecting data quality. The method required no sample dilution or matrix-matching, and long-term stability tests confirmed reliable performance over extended operation. These results highlight the PlasmaQuant 9200 Elite as a powerful solution for routine and high-precision analysis of saline matrices in industrial and environmental applications.
