Meaning and Definition

A chemical substance of known, high purity, used specifically in analytical procedures to detect, measure, or produce other substances.

In a broader sense, any standardised substance used in laboratory analysis to ensure accuracy and reproducibility of tests, often meeting stringent criteria for contaminants.

Dialectal Variation

British vs American Usage

Differences

Spelling is identical. The concept is universal in chemistry. The abbreviation 'A.R.' may be seen slightly more often in British lab manuals.

Connotations

Identical technical connotations of precision, reliability, and controlled quality.

Frequency

Equally frequent in both academic and industrial laboratory contexts in the UK and US. Rare to non-existent in general discourse.

Common Mistakes When Using “analytical reagent”

  • Using 'analytical reagent' to describe any laboratory chemical (it specifies purity).
  • Incorrect pluralisation: 'analytical reagents' is correct for multiple types/bottles.
  • Misspelling as 'analytic reagent' (though sometimes seen, 'analytical' is standard).

FAQ

Frequently Asked Questions

Not exactly. 'Analytical reagent' implies a higher, standardised purity suitable for quantitative analysis. 'Laboratory reagent' (LR) is a more general term and may be of lower purity.

It stands for 'Analytical Reagent' or 'Analytical Grade', indicating it meets specific purity standards for use in analytical chemistry.

You could, but it is often unnecessarily expensive for that purpose. Industrial or technical grade chemicals are typically used for synthesis.

It is countable when referring to types or bottles (e.g., 'three different analytical reagents'). It can be uncountable when referring to the concept or grade (e.g., 'supplied in analytical reagent').

A chemical substance of known, high purity, used specifically in analytical procedures to detect, measure, or produce other substances.

Analytical reagent is usually technical/scientific in register.

Analytical reagent: in British English it is pronounced /ˌæn.əˈlɪt.ɪ.kəl riˈeɪ.dʒənt/, and in American English it is pronounced /ˌæn.əˈlɪt̬.ɪ.kəl riˈeɪ.dʒənt/. Tap the audio buttons above to hear it.
