Precise and Reliable Seawater Analyses
SEAL Analytical are world-wide leaders in the supply of segmented flow analyzers for Seawater community. The high precision and reproducibility, robust design and low detection limit of SEAL analyzers make them the first choice for seawater analysis. Leading seawater laboratory and research institutes use the SEAL AutoAnalyzer and QuAAtro. As well as being reliable laboratory instruments, these analyzers are designed to stand up to tough conditions on board an oceangoing research vessel, and are in routine ship-board use from the Arctic Ocean to the Weddel Sea. The latest instruments use LED light sources which have long life and are unaffected by vibration and are extremely stable. They were developed specifically for trace-level on-board seawater analysis.
