The strong linear correlation observed between S BET and the micropore volume of 190 carbons with pore widths between 0.5 and 1.8 nm confirms the unreliable character of S BET , in spite of its frequent use. (It corresponds approximately to 2200-2300 m 2 per cm 3 of micropores, whatever their width)
## Application of a polarity parameter model to the separation of fat-soluble vitamins by reversedphase HPLC The retention behavior of a series of fat-soluble vitamins has been established on the basis of a polarity retention model: log k = (log k) 0 + p (P m N -P s N ), with p being the polarity o
