QuAAtro39 is the world’s most automated, compact, Continuous Segmented Flow Analyzer. With micro or macro flow hydraulics, heated manifolds, high resolution detectors and advanced software this high performance microflow chemistry analyzer is ideal for the detection of ultra-low nutrients in water, wastewater, seawater, soil, plant extracts, tobacco and wine.
SEAL Analytical has more than 1,000 documented Continuous Flow Analyzer methods, with new applications regularly being developed in our laboratories. USEPA, ASTM, ISO, AOAC, DIN and other international regulatory compliant methods available.
The QuAAtro39 AutoAnalyzer is the very latest generation of the original world-class Technicon Continuous Segmented Flow Analyzer (SFA). QuAAtro39 AutoAnalyzer is now even more flexible and with 33% more capacity over its predecessor, further improving laboratory efficiency.
A basic Continuous Segmented Flow Analyzer consists of an AutoSampler, a peristaltic pump, a chemistry manifold, a detector and data acquisition software. Samples and reagents are pumped continuously through the chemistry manifold. Air bubbles are introduced at regular intervals forming unique reaction segments, which are mixed using glass coils. Glass is ideal, as it is inert, stays clean and enables easy visual checks.
In Continuous Segmented Flow Analyzers reactions run to completion, and the ratio of sample to reagents in the detector reaches a constant maximum value. This results in ultra-low detection limits and exceptional reproducibility. Variations in reaction time, temperature, and sample matrix do not affect the results as they do in other colorimetric techniques, such as Flow Injection Analysis, where the reaction is not brought to completion.
