Mercury Speciation: Enhancing Detection Precision

The well-established and concerning heightened toxicity of organomercury compounds, such as methyl mercury chloride and ethyl mercury chloride, compared to their inorganic counterparts underscores the imperative need for meticulous mercury speciation. This precision is pivotal in averting tragedies reminiscent of the one at Minamata Bay. silver-liquid-mercury

The accurate determination of individual mercury species relies on sophisticated separation techniques, notably High-Performance Liquid Chromatography (HPLC) employing partition or ion chromatography, and/or Gas Chromatography (GC). When complemented with highly sensitive detectors like Atomic Fluorescence spectrometers, these techniques create a robust and cost-effective system for mercury speciation.

In the HPLC mercury speciation process, a purpose-designed column for separating organomercury species is intricately connected to an HPLC pump featuring solvent handling accessories and a manual injection valve. The column’s outlet links to the PSA 10.025 Millennium Merlin, where mercury species undergo oxidation to Mercury2+. Stannous chloride is introduced in the gas-liquid separator, liberating mercury0 vapor, quantified through Atomic Fluorescence spectrometry in continuous flow mode. For seamless automation of mercury speciation, the integration of an autosampler and automated valve becomes an invaluable enhancement.

P S Analytical demonstrates further expertise with the 10.820 Modular Interface, presenting Agilent and Dionex LC options for mercury species separation, utilizing a PSA Millennium Merlin as the detector. This amalgamation of cutting-edge technology ensures undetectable precision in mercury speciation, safeguarding against potential environmental and health hazards.”
