A reference database was used for the estimation of the standard uncertainties resulting from sampling, sample preparation, and analysis of soil samples from a target area in Switzerland. This evaluation was based on an extended reference sampling of

The analysis of solid materials by introducing solid test sampies directly into the graphite furnace of an atomic absorption spectrometer must be regarded as a powerful analytical approach. Even if it is - of course - not the'ultimate method'. After

An automated solid sampling analysis system (SSAS) consisting of a powder sampler, an integrated microbalance, a transport and handling system for the sample boat, a microcontrolling unit for all necessary steps and an appropriate AAS instrument is d

The analysis of samples in a graphite furnace directly from the solid state can be attractive for a number of reasons already discussed in Chapter 1 in detail. Langmyhr [629] pointed out what the solid sampling technique of atomic spectrometry can do

The dosing of small amounts of solid test samples is totally different to that of liquid or slurry test samples in every step of the handling procedure which are separation, quantification and transportation. Using a manual or automatic pipette, all

With the introduction of modern furnace technology and improved background correction such as continuum source, Zeeman and Smith-Hieftje systems, slurry sampling graphite furnace AAS (GF-AAS) became, in a relatively short time, a convenient and incre

The historical survey of direct solid sample analysis (SS) by graphite furnace atomic absorption spectrometry outlined below shows that the development of this method did not take a typical course. While the introduction of many analytical methods wa

The basic experience with solid sampling using the graphite furnace were made with the detection by atomic absorption spectrometry. The methodological tools outlined in Chapter 2 were developed primarily with this analytical technique. Therefore, in

Die Bestimmung von Spurenelementen direkt aus der festen Probe erfullt die wichtigste spurenanalytische Grundregel: Die Probe sollte vor der Analyse moglichst wenig vorbehandelt werden, denn jeder Schritt der Probenvorbereitung erhoht die Gefahr, ein
