column temp. 25 C
mobile phase 0.15 M potassium phosphate monobasic, pH 7.0 with phosphoric acid
flow rate 15, 72, 207 µL/min (2.1 mm ID, 4.6 mm ID, 7.8 mm ID, respectively)
pressure 220, 240, 350 psi (2.1 mm ID, 4.6 mm ID, 7.8 mm ID, respectively)

Description

Analysis Note Smaller column internal diameters (ID) are attractive for reasons of low solvent consumption. However, when adequate sample is available, larger ID analytical columns can be advantageous because they provide better column performance.
