Fast mercury determination in analytical applications

LabAnalyzer 254

Perfect solution for quantitative determination of mercury in aqueous samples and sample digests

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.

    Memory effects are minimized and a high sample throughput is possible thanks to specially selected materials for sample gas conducting components and heating of the optical bench.
