Discrete Analyzer Systems
Experience rapid photometric analysis
Thermo Scientific Gallery discrete analyzers automate photometric (colorimetric and enzymatic) and electrochemical (pH and conductivity) analysis providing fast, reproducible results in a compact, benchtop design. The discrete cell technology allows laboratories to measure multiple analytes simultaneously while reducing total analysis and operator time. The unique low volume cuvette design accommodates small reagent volumes, minimizes reagent waste, and as a result, reduces reagent costs. The discrete analyzers cover a wide range of applications including food and beverage analysis, environmental testing, and industrial quality control. There are over 50 ready-to-use system reagents to further simplify analysis, saving technician time and reducing errors.

What is automated discrete analysis?
Automated discrete analysis is a technique that utilizes colorimetric and enzymatic measurements of several analytes simultaneously from a single sample through photometric analysis. Optional modules for some discrete analyzers can also conduct electrochemical analysis for pH and conductivity, or bitterness in finished beer through fully automated sample preparation and photometric detection. Each individual reaction cell is isolated and temperature is stabilized, enabling highly controlled reaction conditions. Discrete analyzers usually consist of dispensing probes, an incubator, a mixer and a photometry unit.
Typical Automated Discrete Analysis Workflow
After the reagents and samples are prepared, they are loaded onto the instrument and the probes dispense fixed amounts of reagents and samples into the individual cuvettes. Next, the individual cuvettes are loaded into the incubation chamber, then mixed, and finally undergo photometric detection depending on the absorbance of specific wavelengths of light. These data are then interpreted through integrated computers and software platforms.
Other traditional automated techniques, such as continuous flow analysis, segmented flow analysis, and flow injection analysis, are not particularly flexible since dedicated modules are needed for specific chemistries and they typically can run only up to six tests simultaneously with at least two dedicated skilled technicians to monitor the run. Automated discrete analysis is much more flexible, performing many different reactions within a single instrument while simultaneous analyzing multiple analytes and requiring only one technician. Automated discrete analysis is used to analyze a wide range of applications including food and beverage analysis, environmental testing, and industrial quality control.
