Reagents are substances used in methods to cause a change or to observe a change (e.g. an indicator used in determining the end point of a titration). In general, they do not have to be made up as accurately as standards so they can normally be prepared using laboratory equipment such as measuring cylinders and top pan balances. This section provides a checklist of the topics an analyst should know and the technical skills that are required to prepare solutions that are fit for purpose. There are some handy tips and suggestions of practical tests and / or observations that enable the competence of the trainee to be assessed.
