AutoAnalyzer 3 HR

Seal Analytical

Continuous Segmented Flow Analyzer

The SEAL AutoAnalyzer 3 HR is the most recent version of the original AutoAnalyzer ll. It’s designed specifically for colorimetric determination of dissolved nutrients in environmental samples.

Based on air Segmented Flow Analysis techniques (also known as Continuous Flow Analysis), the SEAL AutoAnalyzer 3 fully automates repetitive and complex sample analysis steps, from start-up to shutdown. The SEAL AA3 HR chemistry analyzer can also perform solvent extraction, distillation, gas diffusion, on-line filtration and in-line UV digestion in a continuously flowing stream. SEAL AA3 HR chemistry analyzers are fully supported with a library of over 700 documented applications including USEPA, ISO and ASTM standard methods.

AutoAnalyzer 3 HR


Every part of the AutoAnalyzer 3 incorporates improvements enabled by modern electronics and mechanical technology to bring your laboratory higher performance and lower costs.

The SEAL AutoAnalyzer 3 uses all the advantages of air-segmented flow. With reaction times up to 30 minutes, even complex procedures like distillation can be automated. Dialyzers can be built into the system for elimination of interference from dirty or colored samples. Our proprietary in-line UV digestion procedure conforms to the ISO Standard Methods for automated measurement of Total Cyanide and Total Phosphorus.

Segmented Flow Advantages
Fully Automatic Operation – Start up to Shut down
Ultra Low Detection Limits
40 to 100 samples per hour
over 700 documented applications
Low reagent consumption
Compatible with Technicon and Bran+Luebbe AutoAnalyzer II Systems
Quick Method Change-over
Wide range: dilution of sample is rarely necessary
Modular Design for high flexibility
A one channel SEAL AutoAnalyzer 3 System comprises a Sampler, Pump, Chemical Manifold, Detector and Computer. The system can easily be extended by adding a second Chemical Manifold and a second Detector. The SEAL AutoAnalyzer then becomes a Two Channel System, which measures two different analytes at the same time. Additional Detectors and Manifolds can be added, as required, up to a total of 8 channels.

Dual Range Methods
Most multitest methods are also dual-range; with separate pump tubes for high and low ranges. You can test an extremely wide range of sample concentrations. For example, the AutoAnalyzer 3 method for Nitrate in Seawater can measure up to 8500 ug N/L and has a detection limit of 0.14 ug/L. This same manifold can be used to measure Ammonia and Silicate.
