A New Technique in Paper Chromatography.

Study of phenylketonuria by paper chromatography

Paper Chromatography

In this laboratory exercise we will separate and identify the cations in an aqueous mixture that possibly contains Fe 3+ , Ni 2+ or Cu 2+ salts. The separation will be achieved using Paper Chromatography. Identification of the cations will be affected by simultaneously running separate solutions, each containing a single salt of these ions, through the chromatographic system and comparing the r...

Ion chromatography: a new technique for clinical chemistry.

Ion chromatography is a new analytical technique in which the ions to be analyzed are separated on a special pellicular ion-exchange column. Once separated, the effluent from the separating column passes into a second ion-exchange column, which removes the eluent or buffer ions from the moving phase without removing the sample ions, which are detected and measured by electrical conductivity on ...

Paper Chromatography of Steroids

In Paper I of this series (1) a method was described for the paper chromatographic analysis of certain ketonic steroids as hydrazones formed with Girard’s Reagent T. When that technique was applied to the adrenal cortical hormones, however, certain deficiencies appeared. (a) The RI values of the individual steroid-Reagent T hydrazones were not sufficiently different to permit identification. (b...
