Unit 4: Scientific Practical Techniques

4.1 Analytical Techniques



Scenario:
You have started to work in an analysis laboratory for a chemical company and have been given
two samples to analyse. You will need some training in some basic techniques in quantitative and
qualitative analysis before you can carry out analysis on the two samples (one qualitative and one
quantitative). Record keeping must be done accurately.


Grading Criteria to be assessed:
P1 Carry out quantitative and qualitative analytical techniques.
M1 Explain how accuracy may be ensured in the techniques used.
D1 Evaluate the quantitative and qualitative analytical techniques used, suggesting
improvements for future investigations.

Tasks:


1. Also in the report, evaluate the procedure by identifying any procedural and
measurement errors, and also suggesting ways in which to minimise these errors.

(D1)


Qualitative Analysis
2. Evaluate the procedure by identifying any procedural errors, and also suggesting ways in
which to minimise these errors. (D1)




Plagiarised work will result in disciplinary procedures.
