thin layer chromatography solvent selection crossword

Quality Control of Compounded Radiopharmaceuticals

Solvent selection is based on the ability of the solvent to separate the radiopharmaceutical components on a medium 2 For the mobile phase 0 9% saline 20% saline water methyl ethyl ketone (MEK) acetone and methanol are some of the solvents utilized When thin-layer chromatography is used in Figure 1

THIN LAYER CHROMATOGRAPHY

Note: I'm taking a simple view of the way that thin layer chromatography works in terms of adsorption (see below) which should be adequate for students doing courses for 16 - 18 year olds The reality is more complicated and the explanation will vary depending on what sort of solvent or solvent mixture you are using Some similar problems are discussed on the page about paper chromatography

Introduction to Liquid Chromatography

"drop chromatography" later perfected as Thin Layer Chromatography (TLC) by Kirchner in the U S 1952: Martin and Synge receive Nobel Prize for "invention of partition chromatography" or plate theory to describe column efficiency 1966: HPLC was first named by Horvath at Yale University but HPLC didn't "catch on" until the 1970s

Thin Layer Chromatography

Thin-layer chromatography (TLC) is a very commonly used technique in synthetic chemistry for identifying compounds determining their purity and following the progress of a reaction It also permits the optimization of the solvent system for a given separation problem In comparison with column chromatography it only requires small quantities of the compound (~ng) and is much
