Popis: Stainless-steel porous-layer open tubular (PLOT) columns have been made with Dexsil and other stationary phases suitable for the separation of a range of volatile metal chelates and organometallic compounds. Integrity of the substrate is assured by multiple coating of the stationary phase. Structural isomers of chromium β-diketonates and mixed ligand redistribution products are resolved and eluted without sample loss to flame ionization detection limits. A family of tetradentate copper β-ketoamine chelates are separated and the pyrolysis products of analogous tetradentate salicylaldimine complexes are resolved. Vapor phase infra-red spectrophotometry is used on-line with the PLOT column eluent for peak identification. A range of metallocene organometallics are separated including ferrocene, ruthenocene and osmocene, and substituted ferrocenes are resolved with iron specific detection by d.c. argon plasma emission spectroscopy. Cyclopentadienylmanganese tricarbonyls and cyclopentadienylchromium nitrosyl carbonyl species are also chromatographed.
