Speciation of aluminium in silicon carbide by electrothermal vaporization-inductively coupled plasma atomic emission spectrometry

Quantitative multi-element analysis of Argonne Premium Coal samples by ETV-ICP OES – A highly efficient direct analytical technique for inorganics in coal

“…ally the whole coal should be analyzed directly as solid sample 111 to prevent chemical changes in the sample and consequently the 112 possibility of element speciation is given. 113 As a result of the disadvantages of the traditional methods, 114 there is a growing need for a rapid-process assisted analysis to 115 assess the total content as well as the element distribution in [13,14]. The measurements were performed using two ICP OES spec- which is added to the inner gas phase of the oven (cf.…”

Inductively coupled plasma optical emission spectrometry with axially viewed configuration: an overview of applications

“…This system was used for the speciation of Al in silicon carbide samples. 90 The use of tungsten coil was also proposed as electrothermal vaporizer for ICP OES with axially viewed configuration for Cd determination in urine samples. 91,92 The tungsten coil was extracted from the glass casing of a standard slide projector tube and firmly placed in the laboratory-made mount.…”

Improvements in the direct analysis of advanced materials using ICP-based measurement techniques

“…However, introducing dry powder into small graphite boats is a tedious process and requires experience. One way to better distribute a ne, dry powder across the bottom of the graphite boat, was shown by Hassler et al 46 Aer weighing the dry material in the boat, the authors added a drop of ethanol onto the powder. This helped to distribute the powder inside the graphite boat more homogeneously, and resulted in more uniform vaporization of the sample.…”
