The Analysis of Metal Chelates by Chromatography

Abstract

Grateful acknowledgment is made to the National Research Council of Canada and to the Imperial Oil Co. of Canada for financial support which made possible the purchase of the gas chromatograph.

Solvent Extraction of Beryllium with Trifluoroacetylacetone and Hexafluoroacetylacetone.

“…A long exposure with the accelerating voltage a few tenths of a per cent higher than usual exhibits relatively more intense metastable peaks. However, this intensity increase is not uniform for all metastable peaks and their position on the plate is shifted, as expected on the basis of previous reports (1,3,9) involving electronmultiplier recording. This complicates column (13), and can be determined quantitatively by employing flame ionization (4), thermal conductivity (10), or electron capture detectors (9).…”

“…Solvent extraction of aqueous solutions of copper, iron, aluminum, gallium, indium, and scandium with an organic solution of trifluoroacetylacetone has been successfully employed to prepare solutions suitable for injection into a gas chromatograph (3,5,6,11,12). Beryllium acetylacetonate can also be eluted from a gas-liquid chromatographic column (1). Beryllium trifluoroacetylacetonate, however, is more volatile than beryllium acetylacetonate and consequently can be eluted at lower column temperatures (13).…”

Organometallic chemical vapor deposition of copper oxide thin films

“…In addition to the role of solvent, these reactions often depend on three other [55,56]. Thermogravimetric analysis has been employed in many cases for rapid determination of the thermal stabilities of these complexes.…”
