separation of silver nitrate solution through chromatography

A Guide to the Practice of Analytical Silver Ion thin

Introduction. Silver ion thin layer chromatography (Ag TLC) in analytical mode is the method of choice when the task is to check the purity, to identify fatty acid methyl esters (FAME) or triacylglycerol (TAG) component(s), or to get a picture of the composition of a sample. For the purpose, plate dimensions (most often), layer thickness,

Separation and Identification of Sugars using Paper

Separation and Identification of Sugars using Paper Chromatography. It is claimed that suitable purification of the phenol either reduces the darkening 5 or eliminates it altogether 15. We find that most of the darkening can be avoided by extracting the paper with ether before spraying with the silver reagent. By adopting this slight modification, it has been found unnecessary to purify the phenol.
