refractometryn.

Brit.

/ˌriːfrakˈtɒmᵻtri/,

/rᵻˌfrakˈtɒmᵻtri/, U.S.

/rəˌfrækˈtɑmətri/,

/riˌfrækˈtɑmətri/

Origin: Formed within English, by compounding; originally modelled on a French lexical item. Etymons: refract v., -ometry comb. form.

Etymology: < refract v. + -ometry comb. form, originally after French réfractométrie (1900 in a paper by E. Riegler, in Buletinul Societaţii de Sciinţe Bucureşti 9 251, the source reviewed in quot. 1900), in later use after refractometer n. Compare German Refractometrie (1894 or earlier; now Refraktometrie ). Compare earlier refractometric adj.

Physics and Chemistry.

Measurement of the refractive index of a substance, esp. as a technique of analysis; the use of a refractometer.
