Determination of aluminum and iron by solvent extraction and gas chromatography

Determination of free amino acids by high performance liquid chromatography

“…X-ray fluorescence analysis was carried out on the soil, the condensed chlorides, and the remaining residue (Figure 1). The plutonium concentration of the residue was determined by a procedure given by Schüttelkopf (7).…”

“…Jouniaux(6) investigated the behavior of the fluorides of plutonium and of other transuranium elements under gas adsorption chromatographic conditions. Naumann(7) separated plutonium from uranium by gas chromatographic separation of the chlorides on graphite.…”

Determination of trace levels of iron(III) by homogeneous catalysis and gas chromatography

“…These procedures are based on the formation and gas chromato-graphic analysis of volatile, metal ion-ligand complexes (2)(3)(4)(5). Indeed, Fe3+ levels in several real-world samples have been determined by gas chromatographic analysis of neutral Fe3+ complexes, though analysis has been limited to samples containing microgram levels of iron (6)(7)(8). These procedures have not been extensively applied to routine analyses, however, because of problems associated with the low stability of many of the complexes.…”

Determination of trace quantities of aluminum and chromium in uranium by gas phase chromatography

“…The review of Moshier and Sieviers (1) on the studies made with acetylacetone and volatile compounds, especially fluorine derivatives, was followed by many other publications (2)(3)(4)(5)(6)(7)(8).…”
