Definition

Noun: 1. A type of chemical analysis: Quantitative analysis is a branch of analytical chemistry focused on determining the precise amount or concentration of a specific element or compound present within a substance or sample. It answers the question "how much?" rather than "what is it?".

Usage

Quantitative analysis is a fundamental technique in scientific and industrial fields. It is used to measure the exact quantities of components in a material.

Examples: * The laboratory performed a quantitative analysis on the soil sample to determine the exact concentration of lead. * Quantitative analysis of the alloy revealed it contained 92.5% silver and 7.5% copper. * Researchers rely on quantitative analysis to calculate the purity of pharmaceutical compounds.

Advanced Usage
  • "to perform/conduct a quantitative analysis": This is the standard phrasing for carrying out this type of measurement.
    • The team will conduct a quantitative analysis to measure the pollutant levels.
  • The term is often contrasted with qualitative analysis, which identifies elements or compounds are present without measuring their amounts.
Variants and Related Words
  • Quantify (verb): To measure or express the quantity of something.
    • The study sought to quantify the effects of the treatment.
  • Quantitation (noun): Another term for the process of quantitative analysis, often used in biochemistry and life sciences.
    • The quantitation of proteins in the sample was achieved using a spectrophotometer.
Synonyms
  • Quantitation
  • Quantitative assay
  • Quantitative determination
  • Gravimetric/Volumetric analysis (These are specific of quantitative analysis).
Related Phrases
  • Quantitative data: Numerical data obtained from measurements like quantitative analysis.
    • The quantitative data from the experiment supported the hypothesis.
