Retention behavior of large polycyclic aromatic hydrocarbons on metalloprotoporphyrin-silica stationary phases [PDF]
Fresenius' Journal of Analytical Chemistry, 2001 The retention behavior of large polycyclic aromatic hydrocarbons (LPAHs) (> or = 7 rings) on newly developed metalloplotoporphyrin (MProP)-silica stationary phases is examined and the results are compared to previously reported data for retention of the same solutes on commercially available phases.
