What is a Discrete analyzer?

A discrete analyzer is an automated chemical analyzer in which the instrument performs tests on samples that are kept in discrete cuvettes in contrast to a continuous flow analyzer (SFA and/or FIA) that uses a peristaltic pump for a continuous stream of reagents.

Discrete analyzers have had a long, successful history in the clinical market, and were introduced into the Environmental and Wine markets about a decade ago.

Like other discrete analyzers, Astoria-Pacific’s rAPID-T system is very simple to operate:

  • The Operator selects the test(s) he/she would like to run and enters the Sample IDs and any other pertinent information for the analysis
  • Sample cups and reagent bottles are loaded onto the system
  • The run is started
  • The system uses its robotic arm, sample needle and syringe to mix samples and reagents in replaceable and reaction cuvettes. NOTE: If selected to do so, the system can create a calibration curve from a single stock standard, thereby reducing time and errors related to manual techniques
  • Once the end point of the reaction is completed, the photometer measures the resultant absorbance
  • The data is collected by the rAPID-T software. NOTE: The data can then be exported to your LIMS system or other worksheet

rAPID-T allows for online calibration prep, autodilution of off-scale samples and easy export of data and run files. It is compact, highly versatile and affordable:

  1. Dimensions: 20″ x 24″ x 15″
  2. Weight: 32lbs
  3. Runs common applications for Drinking Water/Waste-Water: Nitrite, Nitrate, Ammonia/Ammonium, Orthophosphate, etc.
  4. Runs common applications for Wine: Acetic Acid, L-Malic Acid, Ammonia, NOPA, Glucose+Fructose, Total Sulfite, etc.
  5. Compact and affordable for any lab
