Advantages of Zeeman over D2: Zeeman background correction does, however, have some advantages over deuterium background correction. 1. Zeeman background correction will correct for some structured background. 2. Zeeman background correction will correct for some spectral interference. 3. Zeeman background correction does not require a second source.
Advantages of D2 over Zeeman: 1. Deuterium background correction does not sacrifice any sensitivity. 2. Deuterium background correction does not decrease the dynamic range of the atomic absorption measurement. 3. Deuterium background correction is less expensive than Zeeman background correction. 4. Deuterium background correction can work under 120 Hz measurement frequencies
