Chemical analysis of substances

The focus of this area at T level is to understand that the chromatography and spectroscopy techniques listed can be used to separate, detect and identify substances and so the emphasis of the teaching in this unit will be on how they do that and not necessarily on typical A level focus areas like what is happening to the bonds or molecules. Most of the techniques used are new to students, although it will be helpful to start with key principles behind them before moving on to the different examples. Some of the  are also picked out as quantifying the components in a mixture and can be compared with the techniques that do not with reasons why.

Whilst this list provides a source of information and ideas for experimental work, it is important to note that recommendations can date very quickly. Do NOT follow suggestions which conflict with current advice from CLEAPSS, SSERC or other recent safety guides. eLibrary users are responsible for ensuring that any activity, including practical work, which they carry out is consistent with current regulations related to Health and Safety and that they carry an appropriate risk assessment.
