PS Analytical’s Mercury Speciation systems take you beyond total mercury measurement to identify and quantify specific mercury species — including highly toxic forms like methylmercury — using advanced chromatographic separation coupled with ultra-sensitive detection. By combining HPLC or GC separation with atomic fluorescence spectrometry (AFS), these solutions let labs distinguish between inorganic and organic mercury species with precision and confidence.

• Toxicity varies by species — methylmercury and other organomercury compounds pose very different health and environmental risks than inorganic forms.

• Regulatory and ecological insight — speciation data supports risk assessment, remediation decisions and compliance with environmental guidelines.

• More detailed analysis — species-specific results help researchers and regulators understand sources, pathways and transformations of mercury in the real world.

How the system works?

• Chromatographic separation: Mercury species are separated using HPLC or GC.

• Conversion to detectable form: Separated species are converted to elemental mercury vapour.

• AFS detection: Ultra-sensitive atomic fluorescence spectrometry quantifies each species down to ultra-trace levels.

• Automated workflow: Autosamplers and software make speciation analysis efficient for routine lab workflows.
