Problem 22-21

A chromatographic procedure separates 4.0 mg of unknown mixture on a column with a length of 40 cm and a diameter of 0.85 cm. (a) What size column would you use to separate 100 mg of the same mixture? (b) If the flow is 0.22 mL/min on the small column, what volume flow rate should be used on the large column? (c) If mobile phase occupies 35% of the column volume, calculate the linear flow rate for the small column and the large column.
