Feasibility of high-frequency field-modulation for Zeeman-modulated atomic-absorption spectrometers.
Some advantages of alternating field modulation for Zeeman background-correction are discussed. A technique for applying such modulation to a conventional hollow-cathode lamp is examined. The technique is used to provide a very simple conversion of a Techtron AA3 spectrometer to Zeeman background-corrected operation.
