- Model LabAnalyzer 254 - Fast Mercury Determination in Analytical Applications

From

0

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.

  • the optical system does not require any readjustment
  • Short analysis time
  • Low reagent consumption
  • Automatic zero adjustment
  • 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.
