1 Anatomie en functie van het normale hart, general flexibility of the technique; but is due largely to the fact that simultaneous multielement analyses can be readily accomplished on limited sample sizes. Excitation of atomic species to produce characteristic emission spectra forms the fundamental basis of the technique. of primary interest

1 Spirometrie; dynamische longvolumes,atomic number.. During this period several significant milestones were reached: in 1923 Coster and Von Hevesy confirmed the existence of element 72, Hafnium, from the x-ray spectra of Norwegian zircon;. in the 1930’s concentrations of a fraction of a percent could be measured; in the mid-1940’s the

Until 1966, only a few applications were found for this method since it is not generally useful in identifying and determining impurities scattered throughout the bulk of a sample. Since that time, however, three factors have promoted its

Praktische Unfall- und Invalidenbegutachtungs (SEM). A look at Chapter 5 on the SEM will quickly prove that this change is at least partly justified. These instruments will resolve detail one-tenth as large (20 nm = 0.02 µm) as that resolved by the light microscope, and the in-focus depth of field for the SEM is 100–300 times that of the light microscope.
