摘要: Abstract We have compared the retention of twelve polycyclic aromatic hydrocarbons (PAHs) on columns packed with octadecyl bonded phases from eight different manufacturers. The capacity ratios and selectivity factors were calculated for each compound every column, under conditions isocratic elution identical mobile phase strength similar linear flow velocities. observed a wide range significantly material. These data did not correlate carbon content or surface concentration alkyl groups various stationary phases. also report characteristics these PAHs manufacturing lots silica used one commercial columns.
