concentrationbased

Concentrationbased is an adjective used in science and technology to describe approaches, systems, or decision rules that depend on the measured concentration of a substance. The term is not tied to a single field and may refer to methods that activate, adjust, or prioritize actions based on concentration thresholds or target ranges.

In analytical chemistry and bioassays, concentrationbased methods signal a response when analyte concentration crosses a predefined threshold; examples include colorimetric assays and optical detectors calibrated to concentration.

In pharmacology, therapeutic drug monitoring uses concentrationbased dosing to keep drug levels within a prescribed range, with dose adjustments guided by plasma or serum concentrations.

In environmental science, concentrationbased sampling or trigger-based monitoring initiates sampling or remediation steps when contaminant concentrations exceed regulatory limits.

In process control and chemical engineering, concentrationbased control maintains product quality by regulating feed or reaction conditions in response to real-time concentration measurements.

In computing or data analysis, the phrase may appear in a looser sense to describe methods prioritizing data points by concentration-like metrics such as density, although this usage is less formal.

Limitations include measurement error, calibration requirements, and the influence of sample matrix. The meaning of concentrationbased can vary by discipline, and precise definition is usually provided by a field-specific context.
