Beer-Lambert c = A/(εl): univariate calibration / multivariate OLS extension

Layer 2 — Chemistryin the chemometrics subtree

Beer-Lambert law A = εcl (Beer 1852; Lambert 1760): optical absorbance is linear in analyte concentration c, path-length l, and molar-absorption coefficient ε. Univariate inversion: measure A, know ε and l, compute c = A/(εl). …
