A new method for absolute analysis in Electrothermal Atomization Atomic Absorption Spectroscopy (ETA-AAS), proposed for aqueous solutions, is extended to matrix modifiers based on palladium and magnesium. The experimental results show that only the P

A simple and rapid wet-digestion procedure is described for the determination of total mercury in botanical samples by cold vapour atomic absorption spectrometry. The method is based on the oxidising properties of potassium dichromate in dilute sulph

Second-harmonic phase-selective a.c. voltammetry and second-harmonic a.c. anodic stripping voltammetry are shown to be particularly suitable for simultaneous determinations of elements having very close half-wave potentials (differences of

A simple model is proposed for the determination of the absolute amount of an analyte when non-destructive detection systems are used in high-performance liquid chromatography and flow-injection analysis. The method requires only a knowledge of the c

The diffusion process is the most important atom transport mechanism in electrothermal atomisation atomic absorption spectrometry (ETA-AAS) with the platform-in-furnace technique. Under specific experimental conditions it can be assumed that it is th
