Planar chromatography

Abstract

Jo*eph Sherma received a B.S. In chemistry from Upsala College, East Orange. NJ. In 1955 and a Ph D. in analytical chemistry from Rudgers University in 1958. His thesis research In Ion exchange chromatography was under the direction of the late Wm. Rieman III. Dr. Sherma joined the faculty of Lafayette College in Sept 1958 and Is presently John D. & Frances H. Larkin Professor and Head of the Department of Chemistry and Is in charge of three courses in analytical chemistry. Dr. Sherma independently and with others has written or edited over 350 papers, chapters, books, and reviews covering chromatographic and analytical methods. His current research interests are In quantitative TLC. mainly applied to lipid analysis, pesticide residues, and food additives. He is editor for residues and elements of the Journal of AOAC International. by continuing to offer periodic instrumental TLC training courses.Also mentioned is the lack of text books on modern TLC. To help overcome this shortage of information, Sherma and Fried edited a comprehensive Handbook of Thin Layer Chromatography (5), which contains 1047 pages and includes 13 chapters on the principles and practice of TLC and 18 chapters on applications written by over 40 expert authors from around the world.Chromatographic analysis plays a vital role in forensic science. A feature article in Analytical Chemistry (6) on analytical methods for detecting fraudulent documents contained a number of examples of the use of qualitative and quantitative TLC in this area. GENERAL CONSIDERATIONSA. Books, Reviews, History, and Student Experiments.A general book on TLC (Al) and books covering planar chromatography in the life sciences (A2) and detection reagents and methods (A3) were published. A new volume on carbohydrates in the CRC Handbook of Chromatography series was published in 1991; this handbook contains considerable TLC, HPLC, and GC data, as well as information on sample preparation and solute detection (A4).The following aspects of planar chromatography were reviewed: resolution and separation capacity (A5), Chromarod-Iatroscan TLC-FID (A6), enantiomeric separations (A7, A8), comparisons of TLC and HPLC chiral separations (A9), applications to diagnosis of inborn errors of metabolism (A10), pharmaceutical analysis (All), clinical analysis (A12), analysis

Molecularly imprinted polymer microspheres for solid‐phase extraction of protocatechuic acid in Rhizoma homalomenae

“…But the separation and extraction of the active components in TCMs are tedious and inefficient because of their complicated matrix and the poor selectivity of conventional separation materials. Much research has been reported to achieve selective interaction with the target molecule by changing the sorption materials [11]. Recently, it has attracted considerable attention that the MIPs were applied as separation materials to extract desired active components directly from the TCMs [12][13][14][15][16].…”

“…It is very difficult to separate them effectively. Thus, much research has been directed toward the variation of the sorption materials to achieve the selective interaction with the target molecule 33…”
