Wastewater Analysis -Recommended Instruments

All around the world, SEAL Analytical analyzer and sample preparation products prepare and measure all types of water quickly, accurately and automatically. Analysis of water samples for regulatory compliance testing is a very important job that requires various pre-treatment steps and holding times for each sample. Because of this SEAL understands that your lab’s need can vary test to test and sample to sample. We aim to help alleviate the stress from your testing procedures by increasing your laboratory’s ability to be both precise and flexible while automating your processes. SEAL has solutions that address: Sample Receiving/ Sample Preparation; Sample Clean-up; Sample Digestion; Sample Testing; Data Handling and LIMS Communication. Please contact us to discuss your situation.

Wastewater Analyzer Options

For laboratories in wastewater treatment plants, private testing laboratories, or research facilities, when you automate your wet chemistry analysis you bring a previously unattainable level of sensitivity, speed and precision to your wastewater analysis. All analyzers are supplied with detailed method descriptions, including reagent make up, flow diagrams, and specific application notes.

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).

  • 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.

Analysis By Probe

Often a tedious and repetitive process, Biochemical (also known as Biological) Oxygen Demand (BOD) automation is a necessity in modern environmental labs. SEAL Analytical offers cost-effective, regulation-compliant, custom solutions for labs with various throughputs and automation requirements.

The MiniLab Robotics BOD Series ranges 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 procedure. With a sturdy frame, encoded motors, and intelligent programming, the MiniLab will maintain alignment and accurately carryout the specified automation solution. The SEAL BOD software is fully customizable. This ensures your laboratory needs and regional regulations can be met. 

SEAL has many other ptions for automating your wastewater testing lab. The multi- parameter MiniLab robotic system can be configured to prepare and automate a range of analytical parameters – all in one system. Ideal for water and wastewater applications, systems range from a simple single parameter unit, such as pH, to a multi probe unit designed to measure many parameters. These can include sample preparation features such as sample splitting and filtration. The MiniLab is compatible with many probe types and titration systems.

Suitable for EPA 405.1, ISO 5815-1, Standard Methods 5210 B, DIN 38 409-H51 etc.
