Need help with 5 Please

The following questions 1-6 relate to the chromatogram shown below, obtained in an experiment to separate 3 components in a mixture using a column of internal diameter 320.0 um (including the stationary phase thickness) and 30.0 m in length. The stationary phase thickness is 3.0 um on each side of the inside wall of the column, as shown in the figure. 320 um Detector Signal (UA) 0.6 1.2 1.8 Time (min) Unretained A 0.57 2.29 tr (mins) W1/2 (mins) B 2.51 .0889 C 2.68 ? 0.0424 0.0850 0

Answer 1

Using data the equation is

w1/2 = 0.02427 t + 0.02865 (obtained from graph between given values in table

So for C

w1/2 = 0.0937
