A kinetic theory of atomisation for atomic-absorption spectrometry with a graphite furnace. Part IV. Assessment of interference effects

Abstract

Interference effects in atomic-absorption measurements using electrothermal atomisation are well known but poorly understood. The effects of variations in the rate of atomisation, the rate of loss of atoms and the efficiency of atomisation on absorbance versus time profiles, in a graphite furnace, have been established. These effects are proposed as a basis for establishing the causes of interferences that occur in atomic-absorption spectrometry using a graphite furnace atomiser.
