    Mass spectrometric analysis of ceramics after decomposition with elemental fluorine (1997)
    Springer
    Microchimica acta 125 (1997), S. 101-105 
    Details
    ISSN: 1436-5073
    Keywords: decomposition ; mass spectrometry ; ceramics ; fluorine ; isotope ratio

    Topics: Chemistry and Pharmacology
    Notes: Abstract The features of a combustion with elementary fluorine for the case of compact SiC ceramics and model substances for boron containing ceramics (H3BO3 and Na2B4O7) were investigated with the aim of their decomposition and analysis. On-line detection of the gaseous decomposition products by quadrupole mass spectrometry using electron impact ionisation was studied. Limitations by blanks and transport interferences were investigated. Standard addition as well as the isotope dilution technique were used for calibration in the case of B, C and W at the trace and major component level.

    On-line electrochemical preconcentration of manganese for graphite furnace atomic absorption spectrometry using a flow-through electrochemical cell (1993)
    Springer
    Microchimica acta 110 (1993), S. 1-12 
    Details
    ISSN: 1436-5073
    Keywords: electrochemical preconcentration of Mn ; flow-through cell ; GF AAS ; water analysis

    Topics: Chemistry and Pharmacology
    Notes: Abstract A flow system incorporating a 2-electrode electrochemical microcell with a working electrode made from crushed reticulated vitreous carbon and a graphite furnace AAS instrument was used for the preconcentration and determination of trace amounts of Mn. The sample, rinsing and elution solutions were pneumatically transported through the system. Mn2+ ions can be quantitatively deposited both anodically and cathodically at a voltage of +1.5 to + 3 V and −2.5 to −4V, respectively applied to the cell. Samples of 0.1 to 1 ml volume were analyzed within 5–10 min. The limits of detection and determination were 8.7 and 29 pg, respectively. The reproducibility was 1.5 to 5%. The electrochemical behaviour of Mn in the flow system was studied by using a 3-electrode flow-through cell coupled on-line to a flame AAS instrument.

    Advanced ceramics and their basic products: A challenge to the analytical sciences (1990)
    Springer
    Microchimica acta 101 (1990), S. 173-188 
    Details
    ISSN: 1436-5073
    Keywords: ceramics ; atomic spectrometry ; inorganic analysis
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract The analytical characterization required in the development and in the quality control of new ceramics is discussed. For the basic substances, the problems encountered in the development of routine techniques for a direct and reliable analysis of Al2O3, AlN, Si3N4, SiC, and ZrO2 powders are reported. Among the atomic spectrometric methods, especially slurry atomization ICP-spectrometry is described. Also the problems encountered in the development of combined procedures as required for the characterization of reference samples are presented. Methods for the direct bulk analysis of ceramics and microdistributional analysis, as they are now under development with laser-based techniques and various probe techniques, are described as well.
