BTEC Level 3 Extended Diploma in Applied Science
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:

Quantitative Analysis

1. Write a report to state and explain what you have done to ensure that the results
obtained for Task 1 are as accurate as possible.
(M1)



Qualitative Analysis

2. State and explain what you have done to ensure that the results obtained for Task 4 & 5
