Biennial Review of Planar Chromatography: 2009–2011

Abstract

The most important advances in the planar chromatography published between November 1, 2009 and November 1, 2011 are reviewed in this paper. Included are an introduction to the current status of the field; history, student experiments, books, and reviews; theory and fundamental studies; apparatus and techniques for sample preparation and TLC separations (sample application and plate development with the mobile phase); detection and identification of separated zones (chemical and biological detection, TLC/MS, and TLC coupled with other methods); techniques and instruments for quantitative analysis; preparative layer chromatography; and thin layer radiochromatography. Selected applications are given in the various sections of the review, especially for modern HPTLC-densitometry.

Bioassay, determination and separation of enantiomers of atenolol by direct and indirect approaches using liquid chromatography: A review

“…Among the various approaches of liquid chromatography, TLC is known for its certain advantages, such as low cost, simplicity of the method and ease of optimization for successful resolution along with facility to photograph the chromatogram as clearly visible evidence of separation. Sherma (2010Sherma ( , 2014 reviewed the literature on application of TLC for enantioresolution in his regular biennial reviews along with advantages of modern TLC in pharmaceutical and drug analysis, comparing with HPLC and HPTLC as well. Application of TLC in enantiomeric analysis has been described in the literature (Bhushan & Martens, 1997;Martens, Günther, & Schickedanz, 1986;Kowalska & Sherma, 2007).…”

Planar Chromatography Mass Spectrometry

“…It does not intend to comprise the meanwhile numerous applications in the individual sections of TLC/HPTLC-MS. 1,17 Only research studies intended for chromatography are considered, which excludes, for example, frontal elution paper chromatography intended for analyzing powders without chromatographic separation.

Differentiating Curculigo Orchioides Rhizoma and Curculigo glabrescens Rhizoma by a Unique New Compound

“…This method may contribute to evaluate herbal medicine, quality, safety and effectiveness. High performance liquid chromatography (HPLC) is the most popular analytical method in separation science and is regarded as one of the gold standard in the authentication of pharmaceutics and herbal medicines due to its good precision, sensitivity and reproducibility [17]. Compared with traditional morphological and microscopic identi cation methods, the HPLC method is relatively faster and more accurate.…”
