The AQ2+ Series

The AQ2+ Series...
Is a flexible analyzer that uses the principle of Discrete Analysis.  Each test occurs in a separate or discrete reaction vessel.

How does the AQ2 Work?
The AQ2+ employs a robust robotic sampling arm working in conjunction with a stepper motor-driven syringe. The syringe is used for aspirating dispensing and mixing accurate and precise quantities of sample and reagent into miniaturized test tubes called reaction wells.

The Sample and reagents are incubated in the reaction wells for a pre-programmed time.  A single aliquot is then transferred into the Optical Quality Glass Cuvette.  The absorbance is read on the reactant in our stationary optical bench to assure the best possible signal to noise ratio.

Programmable Reaction Times
The reaction times are user programmable from seconds to minutes.  We have optimized the SEAL AQ2 Methods to ensure that the chemical reaction is brought to full completion and steady state.  This completed reaction exactly emulates both the Manual and the Segmented Flow Methods. 

Chemistry is brought to full completion
By allowing the chemical reaction to come to a full steady state we eliminate the problems inherent in the Flow Injection Analysis Methodology.  The Flow Injection System does NOT bring the reaction to full completion decreasing sensitivity and potentially introducing kinetic effects. Once the absorbance is read the cuvette is thoroughly cleaned eliminating any carry over or cross contamination
