ENVEA - Model LabAnalyzer 254 - Fast Mercury Determination in Analytical Applications
From Ambient - Air quality monitoring & Laboratory Mercury Instruments
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.
Features & Benefits
- 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
