This lesson covers flame emission spectroscopy in detail, as required by the AQA GCSE Chemistry specification (8.1.2). This is Higher Tier only content, indicated by [H]. Flame emission spectroscopy is an instrumental method used to identify metal ions and measure their concentrations. It is more accurate and sensitive than simple flame tests and is widely used in laboratories and industry.
Flame emission spectroscopy (FES) is an instrumental technique that analyses the light emitted by a sample when it is heated in a flame. Each element emits light at characteristic wavelengths, producing a unique line spectrum that acts like a "fingerprint" for that element.
