Entwicklungsstand und Bedeutung der Aktivierungsanalyse

Abstract: Die Aktivierungsanalyse ist eine der bedeutendsten Methoden für die Spurenanalyse der Elemente und Isotope. Ein besonderer Vorteil der Aktivierungsanalyse ist, daß sie simultane Multielementbestimmungen mit sehr hohen Nachweisvermögen ermöglicht, die für viele Elemente noch unterhalb des ppb‐Bereiches liegen. bei einigen Elementen können noch Mengen in der Größenordnung 10−14 bis 10−15 g bestimmt werden. Bei der Aktivierungsanalyse fallen einige Quellen systematischer Fehler, hauptsächlich die durch den Blindw… Show more

“…Neutron activation analysis has some unique features, mainly the freedom of blank and high sensitivity and the multielement character which make this method very attractive for the analysis of very pure materials (16)(17)(18). The formation of short-lived and medium-lived matrix radionuclides of high radioactivity considerably limits the possibilities of application of "instrumental neutron activation analysis (INAA) to the determination of trace elements in molybdenum.…”

“…Neutron activation analysis has proved to be an extremely powerful method for multielement characterization of high-purity materials. , However, in irradiation of tungsten with reactor neutrons, both short- and long-lived radionuclides of high radioactivity are produced from this matrix which considerably limit the performance of this method. It is completely unsuitable for determinations via short-lived indicator radionuclides, and even the determinations via long-lived indicator radionuclides require radiochemical separations if sufficient limits of detection (LODs) are to be achieved. …”
