Chromatographic Purity of Amino Acids. Arginine

Chromatography

“…However, there is still a considerable volume of new literature on partition chromatography. It is carried out on columns of powdered cellulose (704) and silica gel (554) and on filter paper (103,201,259,271,282,670,741,805,840,841,951,953,960,1016,1072,1185,1188,1209,1217). Novel features include the direct application of acid protein hydrolyzates to the moistened paper, followed by drying in a stream of hot air (513), successive solvent development of biological materials without the removal of salts or proteins (863), and desalting of paper chromatograms by cutting off the starting spot (673).…”

Analytical chemistry

“…The separation of aliphatic primary amines as N-alkyl-3,5-dinitrobenzamides on paper saturated with formamide has been described; 295 amines have also been separated on paper containing an ion-exchange resin.296 Data for multiple paper chromatography of 29 amino-acids are presented. 297 Water-soluble dyes have been studied. Chromatographic data are given for 70 dyes in one publication,298 and 49 in another.299 Cellulose esters and ethers can be separated on paper.3oo The chromatographic behaviour of alkaloids derived from piperidine,301 and of derivatives of barbituric acid,302 has been studied.…”
