Interpretation Introduction

**(a)**

**Interpretation:**

Average number of plates should be calculated.

**Concept introduction:**

Number of theoretical plates is given by following equation:

N = number of plates

t_{R} = retention time

W = width of peak base

Average =

Interpretation Introduction

**(b)**

**Interpretation:**

Standard deviation for the N should be calculated.

**Concept introduction:**

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

Interpretation Introduction

**(c)**

**Interpretation:**

Average plate height of column should be calculated.

**Concept introduction:**

N = plate count

L = length of the packing (cm)

H = height of the column
