Solutions

Chapter 26, Problem 26.14QAP
Interpretation Introduction

(a)

Interpretation:

Number of plates from each plate should be calculated.

Concept introduction:

Number of theoretical plates given by following equation;

N = 16(tRW)2

N = number of plates

tR = retention time

W = width of peak base

Interpretation Introduction

(b)

Interpretation:

Mean and standard deviation for the N should be calculated.

Concept introduction:

Mean = NA+NB+NC+ND4

Standard deviation will give how the values deviate from mean value of N.

Interpretation Introduction

(c)

Interpretation:

Plate height of the column should be determined.

Concept introduction:

N=LH

N = plate count

L = length of the packing (cm)

H = height of the column
