(a)
Interpretation:
Number of plates and plate height and resolution has to be calculated.
Concept Introduction:
Expression to compute number of theoretical plate is as follows:
Here,
It has been found that greater the equilibration steps narrower will be band so this suggests
Expression to compute plate height is as follows:
Here,
(a)
Explanation of Solution
Expression to compute number of theoretical plate is as follows:
Substitute
Thus, number of theoretical plate is
Expression to compute
Substitute
`
Thus, plate height is
Value of
Expression to compute resolution is as follows:
Substitute
Thus, value of resolution is 1.3.
Ratio of plate height is calculated as follows:
Reason behind such massive plate height difference is that rate of longitudinal diffusion is much more rapid in gas than in liquid chromatography.
(a)
Interpretation:
Number of plates and plate height for peak 11 and resolution for peaks 16 and 17 has to be calculated.
Concept Introduction:
Expression to compute number of theoretical plate is as follows:
Here,
It has been found that greater the equilibration steps narrower will be band so this suggests
Expression to compute plate height is as follows:
Here,
(a)
Explanation of Solution
Expression to compute number of theoretical plate is as follows:
Substitute
Thus, number of theoretical plate is
Expression to compute
Substitute
`
Thus, plate height is
Value of
Expression to compute resolution is as follows:
Substitute
Thus, value of resolution is 1.3.
(b)
Interpretation:
Extent of larger plate height has to be calculated and reason behind such massive plate height difference has to be calculated.
Concept Introduction:
Refer to part (a).
(b)
Explanation of Solution
Ratio of plate height is calculated as follows:
Reason behind such massive plate height difference is that rate of longitudinal diffusion is much more rapid in gas than in liquid chromatography.
