colorimetric analysis
Definition
Noun A method of quantitative chemical analysis that determines the concentration of a substance by measuring the intensity of its color, typically using an instrument called a colorimeter.
Usage
"Colorimetric analysis" is a technical term used primarily in scientific fields such as chemistry, biochemistry, environmental science, and medical diagnostics. It describes a specific analytical procedure.
Examples
- The laboratory performed a colorimetric analysis to determine the exact concentration of glucose in the blood sample.
- Colorimetric analysis of the water sample revealed high levels of chlorine.
- This test kit uses a simple colorimetric analysis; a color change indicates the presence of the target compound.
Advanced Usage
- The term implies a process where the amount of colored product formed in a chemical reaction is directly proportional to the concentration of the analyte being measured.
- It is often contrasted with other analytical methods like titration or spectrophotometric analysis, though colorimetry is a form of spectrophotometry focused on the visible light spectrum.
Variants and Related Words
- Colorimetry (n): The science or technique of colorimetric analysis.
- Colorimeter (n): The instrument used to perform colorimetric analysis by comparing the color of a solution with standard colors.
- Colorimetric (adj): Relating to or involving colorimetric analysis (e.g., a colorimetric assay, a colorimetric method).
Synonyms
- Colorimetric determination
- Colorimetric assay
- Color comparison analysis
Related Phrases
- To perform/conduct a colorimetric analysis: The standard phrasing for carrying out this procedure.
- Based on colorimetric analysis: Used to describe findings or methods that rely on this technique.
