Which of the following equations give the expression for the plate number, N when ‘tR’ is the adjusted retention time and ‘Wb’ is the width at the base of the peak which is equal to 4 standard deviations.
A. 16 tR2/Wb
B. 4 tR2/Wb
C. (4tR/Wb)2
D. 4 (tR/Wb)2
Answer:C
Which of the following equations give the expression for the plate number, N when ‘tR’ is the adjusted retention time and ‘Wb’ is the width at the base of the peak which is equal to 4 standard deviations.
A. 16 tR2/Wb B. 4 tR2/Wb C. (4tR/Wb)2 D. 4 (tR/Wb)2
Explanation: The expression for the plate number, N is given as N = (4tR/Wb)2. It is a dimensionless quantity.
