Robert Bunsen and Gustav Kirchhoff developed spectrum analysis as a method of chemical identification. A flame supplied light from the sample; a slit, collimator, prism, and telescope separated and displayed the characteristic lines. Comparing these lines allowed chemical constituents to be recognized even when their ordinary flame colours were difficult to distinguish.[ref]

Robert Bunsen (1811–1899) was a German chemist best known for his contributions to the field of chemistry and for the invention of the Bunsen burner, a common laboratory tool used for heating, sterilization, and combustion. The Bunsen burner provides a flame produced by mixing gas with air, allowing for precise temperature control in various chemical experiments.
