HOWDOES THE QU TRO39WORK?

The QuAAtro39 is the very latest generation of the original world-class Technicon Segmented Flow Analysis (SFA) systems. QuAAtro39 is now even more flexible with 33% more capacity, further improving your laboratory efficiency.
A basic SFA system consists of an autosampler, a peristaltic pump, a chemistry manifold, a detector and data acquisition software. Sample 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 SFA, 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.
QuAAtro39 is a microflow SFA system, the internal diameter of all glassware being 1mm. This reduces reagent consumption and increases throughput, with most methods running at 100 - 120 samples hour.
The integrated enclosed manifold and detector are heated to 37° C. Flow stability is ensured as the optimal bubble frequency for each method is programmed by silent air valves.

How Does the QuAAtro39 AutoAnalyzer Work?

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.
