The Aquakem 250 is easy to use discrete chemistry analyzer
capable of random access or batch analysis and the use of multiple chemistries.
Types of matrices analyzed include clean water, wastewater, soil/sludge digests,
effluents and saline. The Aquakem 250 has automatic start-up and shut down
protocols for true walk-away analysis. No reagent priming is required, enabling
results from the first sample to be available within minutes of starting the
analysis. The Aquakem system can be custom-programmed to meet individual needs
in each laboratory.
Product Detail
The Thermo Scientific Aquakem 250 analyzer provides
convenient automated photometric analysis of water and environmental samples at
an analytical rate of up to 250 tests per hour. All method protocols are based
to those recommended in the standard methods for the examination of water and
wastewater in different countries and those published in the U.K. Blue Book.
Applications include tests, like Ammonia, Alkalinity, Aluminium, Boron, Calcium,
Chloride, Cyanide (post distillation), Hexachrome, Ferrous ion, Magnesium,
Nitrate, Nitrite, Phosphate (ortho and total post digestion), Silica, Sulphate,
Total Hardness, TKN post digestion.
Discrete, selective either random access or batch analysis.
