The NEW AQ1 Discrete Analyzer..
Is a low cost flexible analyzer that uses the principle of Discrete Analysis.  Each test occurs in a separate or discrete reaction vessel.

The AQ1 is IDEAL .. for laboratories with smaller workloads requiring varied tests on different samples and when individual tests are needed immediately.

How do es the NEW AQ1 Work?
The AQ1 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 stop/flow Optical Quality Glass Cuvette.  The absorbance of the reaction is read  in our stationary optical bench to assure the best possible signal to noise ratio.


Programmable Reaction Times
The reaction times are user programmable from second s to minutes.  We have optimized the SEAL AQ1 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 maximise sensitivity and results are less sensitive to reaction changes. Once the absorbance is read, the cuvette is thoroughly cleaned, eliminating any carry over or cross contamination.
