Continuous Segmented Flow Analyzers
Water analyzers can be checking for contamination and water quality to help determine treatment optimization as well as analyzing water samples to verify health-based and aesthetic standards are being met. The automation of your water chemistry analysis will bring a previously unattainable level of sensitivity, speed and precision to your water analysis. All water analyzers are supplied with detailed method descriptions, including reagent make up, flow diagrams, and specific application notes.
Models Suitable for Water Analysis
Water Chemistry Analyzer Methods
- SEAL has an extensive library of over 100 methods for water chemistry analysis.
- USEPA, AOAC & ISO compatible methods available.
- USEPA methodologies for automated colorimetric analysis reference the Technicon AutoAnalyzer II (this model has been replaced by the AutoAnalyzer 3).
- Each method is multi-range, giving the ability to set up your desired range.
- Dialyzers are sometimes used to stop any color interference and/or dilution.
- Methods used with older AutoAnalyzer II and TrAAcs systems are completely transferable to current model AutoAnalyzers.

|Discrete Analyzers make an ideal compact analyzer for the chemistry analysis of water. SEAL has over 30 methods for environmental analysis covering the analytes important in water chemistry analysis.
Discrete Analyzer Models
- AQ1 Discrete Analyzer- Up to 60 tests/hour. Up to 7 tests on a single sample. Compact bench-top analyzer.
- AQ2 Discrete Analyzer- Up to 180 tests/ hour. Up to 7 tests on a single sample. Compact bench-top analyzer.
- AQ400 Discrete Analyzer- High capacity analyzer. Up to 216 tests in one run. 20 cooled reagents, 6 non-cooled. Up to 30% lower detection limits.
Water Chemistry Methods Using Discrete Analysis
- Over 30 methods specifically for the environmental market.
- Our stated detection limits will be achieved by typical laboratories. Many users exceed these detection limits.
- We have individual letters of USEPA approval for SEAL AQ2 & AQ1 methods confirming our methods are acceptable for drinking water (NPDWR/NSDWR) compliance monitoring.
- UKAS methods applied to the AQ2, AQ1 & AQUA 900 Discrete Analyzer are traceable to methods published in the series "Methods for the Examination of Waters and Associated Materials", produced by the Standing Committee of Analysts in the UK. The methods are acceptable for drinking water according to criteria set by the UKAS (United Kingdom Accreditation Service) and the DWI (Drinking Water Inspectorate).
