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.
