Simple determination of uranium by front paper-chromatography

Study of phenylketonuria by paper chromatography

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...

DEVELOPMENT OF A METHOD FOR THE DETERMINATION OF 4-HYDROXY-3-METHOXYMANDELIC ACID (VANILLYLMANDELIC ACID) IN URINE BY PAPER CHROMATOGRAPHY

We have developed a simple and precise paper chromatographic method for the determination of 4-hydroxy-3-methoxymandelic acid (VMA) in urine. Concentrations of VMA in patients with neuroblastoma were increased in comparison to controls. The linearity was excellent in the concentration range tested. The within-assay coefficient of variation for control and patient urine was less than 2.2%. ...

Rapid separation of uranium and plutonium by extraction chromatography for determination by thermal ionisation mass spectrometry

A rapid method based upon extraction chromatography was developed for the separation of U and Pu from solutions of spent nuclear fuel for thermal ionization mass spectrometry. The method involves retention of Pu(iv) and U(vi) on a UTEVA column, thereby accomplishing a separation of these actinides from fission products. A separation of Pu from U was then achieved by selective elution of Pu. Two...
