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

4.Consider the peaks for pentafluorobenzene and benzene in the gas chromatogram shown here.  The elution time for unretained solute is 1.06 min.  The open tubular column is 30.0 m in length and 0.530 mm in diameter, with a layer of stationary phase 3.0 μm thick on the inner wall.  a) Measruing the width, w, at the baseline on the chromatogram, find the number of plates for these two compounds b) Use your answer to (a) to find the resolution between the two peaks c) Using the number of plates N=sqrtN1*N2 with the values from (a) calcuate what the resolution should be and compare your answer with the measured resolution in b
In stationary chromatography, the distribution (K) is the main criterion for the division of species in the sample between the two functions of the system, which factors depend on
(a) In High Performance Liquid Chromatography (HPLC), the separation method is by partition of the solute (analyte) between the mobile phase and the stationary phase. Explain how this leads to separation of analyte mixtures; (b) Describe the structure and materials use in a typical column used for HPLC. Thereby explain why high pressures have to be used in HPLC; (c) Discuss how the need for high pressures also imposes requirements on the injector;
