Flame Emission Spectroscopy

Flame emission spectroscopy is an instrumental method used to identify the metal ions present in a solution and their concentrations.

The process

Place a sample of a metal solution into a flame. Light is emitted.

Spectroscopes

The light that is emitted is captured by a spectroscope.
- This instrument can distinguish between different wavelengths of light to produce a line spectrum.

Flame Emission Spectroscopy Analysis

We can analyse the line spectra produced by flame emission spectroscopy to see which metal ions are present. We can also work out the concentration of the metal ions.

Identity of metal ions

Each metal ion will generate a distinct line spectrum. This means that we can identify all ions present in a solution.

Concentration of metal ions

The intensity of line spectra gives information about the concentration of an ion.

Reference spectra

Unlike flame tests, flame emission spectroscopy allows us to analyse mixtures by comparing them with reference spectra.
