An open tubular column has an inner diameter of 207 micrometers, and the thickness of the stationary phase on the inner wall is 0.50 micrometers. Unretained solute passes through in 63 seconds and a particular solute emerges at 433 seconds. Find the distribution constant for this solute and find the fraction of time spent in the stationary phase.
Consider a chromatography column in which Vs= Vm/5. Find the retention factor if Kd= 3 and Kd= 30.
To improve chromatographic separation, you must:
Increase the number of theoretical plates on the column.
Increase the height of theoretical plates on the column.
Increase both the number and height of theoretical plates on the column.
Increasing the flow rate of the mobile phase would
Increase longitudinal diffusion
Increase broadening due to mass transfer
Increase broadening due to multiple paths
You can improve the separation of components in gas chromatography by:
Rasing the temperature of the injection port
Rasing the temperature of the column isothermally
Rasing the temperature of the column using temperature programming
In GC, separation between two different solutes occurs because
the solutes have different solubilities in the mobile phase
the solutes volatilize at different rates in the injector
the solutes spend different amounts of time in the stationary phase
