Paper Chromatography: Separation and Identification of Five Metal Cations

Most chemists and many other scientists must routinely separate mixtures and identify their components. The ability to qualitatively identify the substances found in a sample can be critical. For example, an environmental chemist investigating samples of polluted ground water will want to know which toxic ions might be present in a sample. Chromatography is one of the first tools employed in su...

The separation of esters of choline by filter-paper chromatography.

7. It is concluded that tran8-tran8-muconic acid is probably a true metabolite of benzene and is not produced in vivo from the ci8-ci8-acid. It is suggested that the 68-c68-acid need not be an intermediate in the formation of the tran8-tranm-acid in the animal body. The expense of this work was in part defrayed by a grant from the Medical Research Council. We are grateful to Prof. R. Cruickshan...

Control of the contaminant level for determination of Al3+ using 8-quinolinol by high-performance liquid chromatography with fluorescence detection.

We developed a technique controlling contaminant Al3+ level using a combination of kinetics and thermodynamics at a pre-column derivatizing step in HPLC. The technique involves modifying a conventional HPLC of 8-quinolinol (Ox) complex with Al3+. The contaminant suppressing reagents, dihydroxyazobenzene (DHAB) and 1,2,3-trihydroxybenzene (pyrogallol) were added to the Ox and pH buffer solutions...
