What is a Discrete analyzer?

Discrete analysis is a technology relatively new to the Industrial market. Special robotics and automated syringes/pumps are used to mix samples and color reagents together, and the resultant color formation is analyzed by a colorimeter/photometer. Although Discrete analyzers does not use a reaction cartridge or chemistry manifold–samples and reagents are mixed together in a reaction wells and/or cuvettes–Discrete manufacturers follow EPA Methods and/or Standard Methods to ensure reproducible results.

Discrete analyzers have had a long, successful history in the clinical market, and use in Industrial markets began in the mid-2000s. Currently there are two different types of discrete analyzers: (1) a system that mixes its sample and reagents in a reaction cup and then analyzes the sample in a separate  optical well or cell; and (2) a system that mixes its sample and reagents in the same cup that the system uses to analyze the sample.

Astoria-Pacific’s Discrete Analyzer uses the latter approach: Sample test tubes and reagent bottles are loaded onto the system; the system uses its robotic arm, sample needle and syringes to aspirate samples and reagents and dispense them into inexpensive and replaceable reaction wells; and then the onboard photometer measures the absorbance through each reaction well.

The Astoria Discrete is an ideal system for a variety of industries. We currently sell these systems to wineries and wastewater laboratories.
