Neutron activation analysis of plantinum converter and furnace mattes using a D-T sealed tube neutron generator
Neutron activation analysis (NAA) has been applied to furnace matte and converter matte samples with the objective of studying the natural variation in the elemental composition of the samples, with a view to characterize the samples for their source of origin. The experimental work was carried out …

Distribution of Five Elements in Lignite Liquefaction Process Streams
… in major flow streams were accomplished by both Neutron Activation Analysis (NAA) and Atomic Absorption (AA) methods of analysis. Element concentrations and process streams flow rate data were used to calculate element material balances for each element analyzed on four different process …

Bromide residues in tissues from rats maintained on diets fumigated with methyl bromide
… abdominal fat, blood and tibia were analyzed by neutron activation analysis (NAA) for bromide residues. A computer program was designed to convert the NAA data to ppm bromide. There was a significant difference in the levels of bromide in the tissues between all treatments in both experiments. …

Physical adsorption of argon, krypton and nitrogen on iron and pyrex at very low pressures
… Analyses via Electron Spectroscopy for Chemical Analysis (ESCA), Scanning Electron Microscopy (SEM), and Neutron Activation Analysis (NAA) were made to characterize the solid sample surfaces. Both Pyrex and iron surfaces were degreased with ethylene dichloride. The iron surface was further …

Incident-response monitoring technologies for aircraft-cabin air quality
… X-ray energy dispersive spectroscopy (EDS) and neutron activation analysis (NAA) were used for elemental analysis of filters, and gas chromatography interfaced with mass spectrometry (GC/MS) was used to analyze used filters to determine TCP isomers. The filter analysis study involved 110 used …
