Applications of the zeeman effect to analytical atomic spectroscopy-VII Line interferences
1Trace Analysis Research Centre, Department of Chemistry, Dalhousie University, Halifax, N.S., Canada.
Abstract:
Equations are developed to describe the response of Zeeman-modulated spectrometers to a line background-absorption interference. The treatment is used to demonstrate that the analyte sensitivity is identical but the line background-responses are different for source-modulated and atomizer-modulated spectrometers. Two correction procedures are developed, the applicability of which depends on the separation of the zero-field source line and the interfering absorption line. Experimental data are shown for the interference of Co in the determination of Hg and of Pt in the determination of Fe.

Atomic Absorption Spectroscopy: Interference
Spectral interference occurs when signals from other elements or molecules overlap with the analyte signal, falsely elevating or masking the analyte's absorbance. This interference can be corrected using Zeeman,...

As Δν decreases and the signals move closer, the doublets appear increasingly distorted. The intensities of the inner lines increase at the cost of those of the outer lines as the signals are slanted or...
