The Quantitative Analysis of Sugars by Paper Chromatography

Study of phenylketonuria by paper chromatography

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...

Analysis of Sugars by Micellar Liquid Chromatography with Uv Detection

A micellar liquid chromatographic procedure is described for simultaneous determination of sugars previously derivatized with 4-aminobenzoic acid ethyl ester (4-ABEE). The optimized conditions, determined by use of the super-modified simplex method, were temperature 30°C, mobile phase containing 17.3 mM sodium dodecyl sulfate, 0.01 M phosphate buffer, pH 6.69, and 7.73% (v/v) ethanol, and UV de...

Determination of monoamino monocarboxylic acids by quantitative paper chromatography.

Many methods for chromatographic separation of amino acids are now available, but their subsequent determination, generally employing ninhydrin, often leaves much to be desired. It was felt, therefore, that there was a need for a simple method of analysis based on the convenient paper technique and employing some means of determination less fickle than ninhydrin colorimetry. The method now pres...
