Determination of fluorine by neutron activation analysis

The analysis of fluorine by instrumental neutron activation analysis is hampered by the short half-life (11.41 s) of fluorine-20 and by frequent interference from chlorine. A procedure is described which mitigates these problems. Using this procedure, Teflon standards were analyzed and an estimated...

Zusammenfassung:	The analysis of fluorine by instrumental neutron activation analysis is hampered by the short half-life (11.41 s) of fluorine-20 and by frequent interference from chlorine. A procedure is described which mitigates these problems. Using this procedure, Teflon standards were analyzed and an estimated minimum detectable weight of 14 ..mu..g of fluorine was determined.
