Absolute values of the slopes measured at various flow rates from the logarithmic decay profiles obtained on a 2.5 mm × 2.1 mm I.D. control column (■) or HSA column (◆) containing 7 µm silica particles. The injections consisted of 100 µl of 10 µM racemic warfarin made at 25°C and using pH 7.0, 0.10 M potassium phosphate buffer as the mobile phase.
