A. The hollow cathode lamp cathode material is made up of Calcium and Magnesium alloy. When running this lamp in an Atomic Absorption spectometer you must tune the instrument to the appropriate wavelength of each element you wish to analysis. So for a Ca/Mg lamp, tune your instrument first to 422.7nm for Calcium and then to 285.2nm for Magnesium or vica versa.
