- Fish liver oil is a strong source of vitamin A, should be measured spectrophotometrically at a wavelength of 329 nm.
- The wavelength 329 nm is utilized because it maximizes the sensitivity to light absorption by vitamin A while reducing interference from light absorption by other components of cod liver oil.
