ENVEA's LabAnalyzer 254 mercury monitoring system, designed for precise and reliable laboratory measurements of mercury concentrations. The compact and advanced design features intuitive controls and high-performance capabilities, ideal for environmental and industrial applications requiring accurate mercury analysis.

LabAnalyzer 254

Fast mercury determination in analytical applications

The LabAnalyzer is the perfect solution for quantitative determination of mercury in aqueous samples and sample digests in the laboratory.

 

In contrast to a typical multi-element AAS the LabAnalyzer 254 is specially designed for elemental mercury. This allows top performance in analytical applications. The use of a specially developed highly stable mercury lamp in connection with thermostat-controlled UV sensors results in a detection limit of a few ppt of mercury.
