Elements and compounds can be detected and identified using instrumental methods these are accurate, sensitive and rapid

Flame emission spectroscopy is an example of an instrumental method used to analyse metal ions in solutions

• The sample is put into a flame and the light given out is passed through a spectroscope
• The output is a line spectrum that can be analysed to identify the metal ions in the solution and measure their concentrations
