AQ2 Discrete Analyzer

AQ2 Discrete Analyzer

This compact, bench-top analyzer completely automates sample testing in laboratories requiring many and varied tests on different samples and/or individual results needed in a short time. Unlike many Discrete Analyzers the SEAL AQ2 has been designed specifically for testing environmental samples, including water, soil and plant extracts. For environmental laboratories considering updating or purchasing new laboratory testing equipment the AQ2 Discrete Analyzer will give you the best analysis and eliminate problems inherent in analyzers designed for clinical use. With the largest installed base of Discrete Analyzers in the USA we continue to develop the software and hardware for the specific needs of environmental samples.

Why Select the AQ2 Discrete Analyzer for Your Lab Automation?

The SEAL AQ2 has:

  • High throughput
  • Lowest detection limits
  • Scheduling of 1 to 7 tests on a single sample with any analyte in any order
  • Better reproducibility
  • Auto dilution- performing two dilutions automatically on off-scale samples. Pre-dilutions can also be scheduled.
  • The chemical reaction is brought to full completion emulating manual and segmented flow methods.
  • Ultra low reagent consumption
  • Carry over and cross contamination eliminated
  • Add samples after a run has started
  • Test programmable per sample to reduce analysis time
  • Completely unattended operation ideal for overnight-programed runs.
  • Methods have USEPA approval for both wastewater and drinking water.
  • UKAS methods are equivalent to "UK Blue Book"
  • Methods specially optimized for soil analysis.
  • The best value Discrete Analyzer on the market

Discrete Analyzer Methods

The broad range of methods for the SEAL AQ2 Discrete Analyzer include analytes important for environmental laboratories analyzing water, wastewater, soils etc. Methods include:

  • Alkalinity
  • Ammonia
  • Chloride
  • Cyanides
  • Nitrate/ Nitrite
  • Nitrite
  • Phenolics
  • Phosphate, ortho
  • Phosphorous, total
  • Silicate
  • Sulfate
  • Total Kjeldahl Nitrogen
  • And more.

How Does the SEAL AQ2 Discrete Analyzer Work?

  • The SEAL AQ2 uses a robotic sampling arm, and a stepper-motor driven syringe to aspirate, dispense and mix precise quantities of sample and reagent into miniaturised test tubes (reaction wells).
  • Samples and reagents are incubated in the reaction wells for a pre-programmed time.
  • A single aliquot is transferred to the stop/ flow optical quality glass cuvette The absorbance is read in the stationary optical bench for the best signal to noise ratio.
  • Reaction times are programmable from seconds to minutes, with the optimized methods bringing the chemical reaction to full completion and steady state, emulating manual and segmented flow methods.
  • Once the absorbance is ready, the cuvette is automatically and thoroughly cleaned, eliminating carry over and cross contamination
