“…The solvent flow may be accelerated in ascending chromatography by keeping the paper inclined (239) and reduced by cutting the paper into certain shapes (1734) Development at elevated temperature is more rapid and gives better results than at room temperature (288). One new preparative technique is based on radial development (1688) and another one, called stereochromatography, on ascending development in a block of compressed cellulose powder (1546).…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
