UNIT 2
MODULE 2: ANALYTICAL METHODS AND SEPARATION TECHNIQUES

GENERAL OBJECTIVES

On completion of this Module, students should:

1. appreciate that all measurements have some degree of uncertainty that is related to both the
measuring device and the skills of the operator;

2. understand the basic theoretical principles of selected methods of analysis and separation
techniques;

3. demonstrate a knowledge of the basic equipment and operational procedures, as well as carry
out experiments associated with selected methods of analysis and separation procedures;

4. use experimental data to quantify substances or elucidate partial structure; and,

5. demonstrate an awareness of the wide applications of various methods of analysis and
separation techniques in industry and in medicine by citing examples.

ACTIVITIES

1. Uncertainty in Measurements

Students should be able to:

1.1. apply appropriate concepts Definitions required for:
to the analysis of scientific mean, standard deviation,
data; precision, accuracy,
calibration curves, and
standards.

Calculation of the mean
and standard deviation
from data provided will be
required.

1.2. carry out experiments to Perform experiments
assess the degree of which should include the
uncertainty in use of pipettes, burettes,
measurements associated volumetric flasks,
with the use of certain thermometers, top-loading
common pieces of balances and analytical
laboratory equipment; and, balances.
