EPA -ISO - ASTM - Discrete Analyzer




Nordtest provides discrete analyzer that automates the sample & reagent pipetting into the cuvettes, mixing, heating and measuring of the reaction product.
With discrete analyzer we complement our range of products for the automation of colorimetric analysis, which already consists of the continuous flow analyzer and robotic analyzer.

Typical Applications

Discrete analyzers are ideal for the analysis of many different colorimetric analyses on a variety of sample types and matrices found in today's environmental laboratories. Typical application areas for the discrete analyzer are for example drinking water, wastewater, ground water and surface water.

AQ400 Discrete Analyzer

Your environmental analytical chemistry has just got easier with the SEAL AQ400 Discrete Analyzer . This compact, bench-top analyzer
has been designed by chemists to address the needs of environmental laboratories requiring high levels of automation, a wide range of chemistries, limits of detection that ensure compliance with regulatory requirements and integration with LIMS systems.
Like the other Discrete Analyzers in the SEAL range, the AQ400 will give you the best analysis and eliminate problems inherent in analyzers designed for clinical use. SEAL Analytical has the largest installed base of Discrete Analyzers in the USA and we continue to develop the software and hardware for the specific needs of environmental samples.

The AQ400 gives you:

- The ability to use as a standalone spectrophotometer - ideal for COD.
- Very high capacity.
- Silent operation.
- Advanced robotics for faster sample preparation/ hour.
- No carry-over or cross contamination.
- EPA recommended optically pure and inert glass cuvette.
- Optional longer path length. Standard 1cm path length.
- Lower detection limits.
- Easy maintenance & easy change syringe
- Cooled and non-cooled reagent positions
- Prepares up to 10 working standards for the calibration curve.
- The chemical reaction is brought to full completion emulating manual and segmented flow methods.
- Ultra low reagent consumption.
- Add samples after a run has started.
- Tests 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 equivalent to "UK Blue Book"
