Method for determining chemical constituents in an electrolysis cell for the production of metal, in particular aluminum, involving the use of light spectroscopy such as Raman spectroscopy that analyses the light emitted from the cell constituents and represents the light as a spectrum, wherein the analysis is performed directly in the cell while the cell is in its production mode, whereby the spectrum is analysed on the basis of reference spectrums based on known compositions, to determine chemical constituents in the cell. Also provided is an apparatus for performing this method. |
