Continuous Segmented Flow Analyzers

Water, Seawater, Wastewater, Soil & Plant, Fertilizer, Food, Wine & Tobacco

Designed Specifically For Environmental Samples

SEAL Analytical AutoAnalyzers have been designed specifically for environmental sample analysis. The current range of SEAL AutoAnalyzers have been developed from the world's best known and most successful Continuous Flow Analyzer- the AutoAnalyzer II . The original AutoAnalyzer II is the instrument that most EPA methods reference for automated colorimetric analysis.

SEAL AutoAnalyzers perform automated wet chemistry analysis using a special flow technique called "continuous flow analysis" or more correctly "segmented flow analysis" fully automating repetitive and complex sample analysis steps from start-up to shut-down. Continuous or Segmented Flow Analyzers have been developed for running a few parameters on a large and very large number of samples. These analyzers provide maximum sensitivity by ensuring the reaction always goes to completion, and with digital true dual-beam detection system with real-time referencing, the highest reproducibility and very lowest detection limits are achieved- features unique to SEAL analyzers and designed specifically for environmental samples like water, wastewater, seawater, soil, tobacco, plant, fertilizer, food and wine.
