2 Instrumental analysis
E.g. Aluminium can build up in dialysis machines very quickly and affect their function. Water used in these machines must be tested for aluminium Although bench based techniques have their place, many companies in today’s world require quick and accurate analysis of their products. For example, a company may need to know the exact chemical composition of their product to check it against legal guidelines, or for safety reasons. E.g.2 Alcohol may affect how we react to certain medicines In these situations there is no room for human error, so a more technological approach must be taken. Machine based methods have a number of advantages over older methods: However, there are also some disadvantages

3 Atomic absorption spectroscopy
What is this instrumental method used for? How does it work? How are the results displayed? Insert a picture of an Atomic Absorption Spectrometer Why is this better than a similar bench based method?

4 Mass spectroscopy What is this instrumental method used for?
How does it work? How are the results displayed? Insert a picture of a Mass Spectrometer Why is this better than a similar bench based method?

5 Chromatographic methods
Chromatography is a method of separating out elements depending on how well they dissolve in a solvent. Use the internet to research and provide a short paragraph of information on the methods below. You need a brief overview of how each one works to separate out the elements in different compounds. Gas-liquid chromatography Gel permeation chromatography Ion-exchange chromatography High performance liquid chromatography
