Measurements on the Level of the Determination Limit in Electrothermal Atomic-Absorption Spectroscopy with Zeeman Correction of the Background

摘要

Theoretical and experimental study of the possibility of minimization of the measurement error in the vicinity of the determination limit of electrothermal atomic-ab-sorption spectroscopy is carried out. New algorithms of data processing providing reduction of the determination limit are developed and tested. Examples of Cd determination in blood, sea water; and urine ant given. It is shown that optimization of the measurement prosedure substantially reduce the limit of determination.
