The write-up says “A C18-silica column is used in this experiment, a 0.46 x 15 cm column with 5-µm particles. Equilibrate the column with 20 empty column volumes of 0.010 M phosphate buffer (pH 7.2) at a flow rate of 1.2 mL/min before beginning chromatography.” Show the calculation for how much mobile phase you would use (volume) and how long it will take to equilibrate the column.
