Culberson, CF/ Johnson, A 1976: A standardized two-dimensional thin-layer chromatographic method for lichen products. - Journal of Chromatography128: 253-259. [RLL List # 97 / Rec.# 3755] Keywords: TLC/ TWO DIMENSIONAL/ CHEMSITRY/ TECHNIQUES
Abstract: 2 figures. 1 table. ["Two-dimensional thin-layer chromatography is useful for microchemical studies on mixtures difficult to resolve by the standardized one-dimensional thin-layer chromatographic method now commonly used for lichen products. A modified two-dimensional technique uses the large body of standardized Rf data already accumulated for these compounds."]
