The quantitative separation of estrogens by paper partition chromatography.
The varying success of known chromat’ographic procedures for the separation and identification of microquantities of estrogens (1, 2) has led to the development of paper partit!ion chromatographic techniques which are reported here. These t’echniques permit rapid separation, identification, and quantitative estimation of free est.rogens in biological materials. The solvent systems of o-dichloro...

The example of column chromatography (Figure 1) demonstrates the typical features found in this analytical technique. The diagram shows an experiment where a two-component mixture is subjected to column chromatography. The column is packed with a solid material called the stationary phase. A liquid solvent or eluting solution is poured into the column and completely wets the solid packing mater...

A reaction scheme has been devised according to 3 RX + 3 Ti(III) + 0.25 P4→ PR3 + 3 XTi(IV) wherein RX = PhBr, CyBr, Me3SiI, or Ph3SnCl with contrasting results in the case of more hindered RX; the scheme accomplishes direct radical functionalization of white phosphorus without intermediacy of PCl3. It is known that P4, white phosphorus, has excellent properties as a trap for carboncentered rad...
متن کاملPaper 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...
