Etymology: < quantitative adj. + analysis n. In sense 1 after German quantitative Analyse (1810 or earlier in a chemistry context); compare French analyse quantitative (1807 or earlier in a chemistry context), Swedish kvantitativ analys (1812), and qualitative analysis n. at qualitative adj. Compounds.

1. Chemistry. Measurement of the amounts of constituents present in a substance. Cf. qualitative analysis n. at qualitative adj. Compounds.
