(d) The resolution for each adjacent pair of compounds.

Problem 27-22

A GC column was operated under the following conditions:
column: 1.10 m x 2.0 mm, packed with Chromosorb P; weight of stationary liquid added, 1,40 g; density of liquid, 1.02 g/mL pressures: inlet, 26.1 psi above room; room, 748 torr measured outlet flow rate: 25.3 mL/min temperature: room, 21.2°C; column, 102.0°C retention times: air, 18.0 s; methyl acetate, 1.98 min; methyl propionate, 4.16 min; methyl n-butyrate, 7.93 min peak widths of esters at base: 0.19, 0.39, and 0.79, respectively

Calculate

(a) The average flow rate in the column.

(b) The corrected retention volumes for air and the three esters.

(c) The specific retention volumes for the three components.

(d) The distribution constants for each of the esters.

(e) A corrected retention volume and retention time for methyl n-hexanoate.
