Gel Chromatography of Condensed Phosphates

The principles of the application of gel chromatography are discussed, together with its potentialities in the investigation of inorganic polymers of phosphorus with the aim of determining molecular dimensions, fractionating a mixture, obtaining individual phosphates, and also analysing their molecular-weight composition. The development and the achievements of the gel chromatography of condensed phosphates are surveyed. The phenomena occurring in a gel during the elution of inorganic compounds are described for several salts. A list of 91 references is included.
