Calculate the phase ratio for a 30 m by 0.2 mm diameter capillary column coated with a 0.5 μm film of stationary phase:
(b) If a similar column uses a 2.0 μm film of the same stationary phase, how will k' change?
(c) Will tm differ between columns a and b if operated the same way?
(d) If tm for the column in a is 1.5 min and a peak has a tr on it of 3.5 min, what will be the tr of that peak on the column in b?
