Molecular formula :
nature : also known as Zander index, UV-visible spectrophotometry, and the sensitivity of a form of expression. The index HPVs Zander made in 1959. He sensitivity of the color reaction : the definition of the cross-section units Plumes can detect the smallest amount of material that units are μ g/cm3, the optical path of 1cm, and the measured absorbance of 0.001, per milliliter of solution of the unknown a few micrograms of material. Zander sensitivity for many metals photoelectric colorimetric analysis. Their values at 0.001 g/cm3 ~ 0.01 μ, within molar absorption coefficient for the relationship between S ε = M / ε (M molecular weight of unknown substances).
