AQ300 Discrete Analyzer

SEAL Analytical | Ion Analysis/Colorimetry

The AQ300 is a low cost flexible analyzer that uses the principle of discrete analysis where each test occurs in a separateor discrete reaction vessel.

The AQ300 robotic sampling arm works in conjunction with a stepper motor-driven syringe that is responsible for aspirating, dispensing and mixing accurate and precise quantities of sample and reagent in miniaturized test tubes called reaction wells.

The sample and reagents are incubated in heated reaction wells until reaction is complete. A single aliquot is then transferred into a 10mm path length optical glass cuvette. The absorbance is read on the stationary reactant to ensure the best possible signal to noise ratio.

Each sample is read is the same position in front of the detector in the 10mm glass cuvette, similar to SEAL colorimetric flow systems, known for their high reproducibility and lowest detection limits. This eliminates issues of reaction well variability and scratching found in direct read discrete systems so improves reproducibility. In the SEAL AQseries, liquid is moved, not the tray - fewer moving parts equals higher reliability.

Once the absorbance is read, the glass cuvette is thoroughly cleaned and checked,ensuring no carryover or cross contamination.
