You are a newly appointed technical assistant at a large
chemical plant, Chemcalequip. As part of your induction
period and to progress in your role, you have to demonstrate
skills in a range of practical procedures and techniques. The
Vocational Scenario or company is often required to identify substances.
Context You need to demonstrate that you can carry out different
chromatographic techniques to separate and identify
components in mixtures. In a report of the techniques you
have used, you will need to explain the techniques, analyse
and evaluate your results and suggest improvements.


Task 1 Evaluate the chromatographic techniques you have
used in relation to the outcomes.
Demonstrate safe working practices and a high level of
proficiency when using the following chromatography
techniques;
 paper chromatography of extracted plant pigments
 Thin layer chromatography, TLC, of extracted plant
pigments
 paper chromatography of amino acids.
Repeat any separations where you can justify a lack of
satisfaction with the quality of the separation obtained.
Produce a report to include :
 an evaluation and analysis of the links between the
chromatography techniques used and the
chromatograms produced.
 conclusions about the components and their effect on
separation leading to the results obtained.
 results from the paper chromatography and TLC of
