Fast mercury determination in analytical applications

LabAnalyzer 254

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.
  • For analyses according to DIN 38406-12 / EPA 7470A / EPA 7471A)
  • Measuring range:0.01 ppb … 10 ppb (10 ng/l to 10 µg/l)
  • Hg trap: Mercury vapors cannot escape into the lab
  • Upgradable to VM-3000 Mercury Vapor Monitor
  • Water samples: drinking water, waste water, ground water, surface water, sea water
  • Soil and sludge samples
  • Geological sample material
  • Waste samples: glass, construction rumble, contaminated liquids, wood
  • Incineration plant monitoring: smoke gas scrubber water, smoke gas analysis (e.g. to VDI 3868-2 VE)
  • Monitoring of foodstuffs
  • Clinical samples: urine, saliva
  • Chemical industry: environmental protection and quality control
  • Petrochemical industry
  • Scientific research
