SEAL Segmented Flow Analyzers and SEAL Discrete Analyzers can be used for checking for contamination and water quality and to help determine treatment optimization as well as analyzing water samples to verify health-based and aesthetic standards. 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.

Discrete Analyzer

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.  

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 confirming our methods are acceptable for drinking water (NPDWR/NSDWR) compliance monitoring. 
• UKAS methods applied to our Discrete Analyzers 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).

Segmented Flow Analyzer 

Typical Water Parameters

We have an extensive list of methods for water chemistry analysis. The list below is a partial list of the most common methods. Contact us for a complete list.

• SEAL has an extensive library of over 100 methods for use with SEAL Segmented Flow Analyzers.
• 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• USEPA methodologies for automated colorimetric analysis reference the Technicon AutoAnalyzer II (this model has been replaced by the AutoAnalyzer 3).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.

Multi-test manifolds

• Multitest manifolds will allow you to analyze a large number of different parameters on a single channel AutoAnalyzer.
• Multitest manifolds extend any size AutoAnalyzer to a multiple channel analyzer.
• Lowers your purchase and maintenance costs, saves space.
• When changing from one test to another only the reagents & the colorimeter filter needs to be changed, saving time as well.
• List of Multitest Methods for water analysis using an AutoAnalyzer.
• List of Multitest Methods for water analysis using the QuAAtro.

Often a tedious and repetitive process, Biochemical Oxygen Demand (also known as Biological Oxygen Demand) automation is one of the most common applications for water laboratories.  SEAL Analytical offers cost-effective, regulation- compliant and custom solutions for labs looking to automate BOD analysis and to avoid the associated tedious, time consuming, error prone tasks involved in manual analysis.

The MiniLab Robotics BOD Series provides automated BOD options for all size labs, ranging from compact models with 12 bottle capacity to larger custom models handling thousands of bottles per day. The robotic arms can be customized to handle multiple steps in the BOD analysis procedure. With a sturdy frame, encoded motors, and intelligent programming, the MiniLab Robot will maintain alignment and accurately carryout the specified automation solution. 

The SEAL BOD software is fully customizable, making automated BOD simple and reliable. This ensures your laboratory needs and regional regulations can be met.
