“…A (3:2) mixture of CF3CCI3-CH2CI2 is recommended for eluting volatile materials from alumina or silica columns (59). A modified method of Celite partition chromatography was published (1645), and an interesting partition column was constructed from compartments separated by differentially permeable partitions (98). The dry column technique uses TLC adsorbents; resolution comparable to TLC is claimed when development is stopped before the solvent reaches the bottom of the column (1180).…”

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.
