Segmented Flow Analyzers: Reliable, Powerful Analysis

SEAL’s AutoAnalyzer systems provide robust and proven nutrient analysis using segmented flow analysis (SFA), a similar method to flow injection analysis (FIA) and another form of continuous flow analysis (CFA). This results in an easy transition for labs familiar with flow injection (FIA) methods and is ideal for labs requiring ultra-low detection limits, maximum reproducibility, and simultaneous analysis.

Familiar Technology: Short learning curve for former FIA users.
Fully Automated: Automatic start-up and shutdown improve lab efficiency.
Superior Performance: Lowest detection limits with exceptional reproducibility.
In-line Gas Diffusion: Eliminates manual distillation for ammonia, TKN, and cyanide methods.
High Throughput: Multiple channels enable simultaneous detection for increased productivity.
