UCT’s Refine™ ultra-filtration columns assessed for sample preparation in the determination of methylmercury and inorganic mercury species in whole blood

UCT’s Refine™ ultra-filtration columns assessed for sample preparation in the determination of methylmercury and inorganic mercury species in whole blood

ByUCT

Biomonitoring measures the amount of a chemical substance and its metabolites in biological samples. It can be used to assess the bioavailability and exposure of humans and other animals to these chemicals. For example, prolonged mercury exposure can result in adverse effects on the central nervous and renal systems. Different species of mercury have different…
