Column and Thin Layer Chromatography Beverly Abstract: Plant pigments were separated and concentrated from a crude spinach extract through the use of column chromatography and an eluatropic series of hexanes‚ hexane/acetone‚ and methanol. The pigments were analyzed using thin layer chromatography with a 30% ethyl acetate/hexane developing solvent. Introduction: Chromatography is a technique used to separate a mixture of two or more components based on

Abstract Gravimetric analysis describes the methods for finding the chemical constituent of analyte in a solution through analytical chemistry. This method uses the mass of solid SO42-‚ with an unknown quantity and quality‚ to qualitatively determine the makeup of the solid SO3-. Two separate experiments with the initial compounds of BaCl2 and SO42- were put into solution to allow for the BaSO4 precipitate to form. Through filtration and ignition of precipitate containing ashless papers

SAMPLE PREPARATION METHODS FOR LIQUID SAMPLES Table of Contents SAMPLE PREPARATON Analytical procedures consist of numerous stages‚ the most important of which is the collection of a sample and its preparation for analysis as samples are usually not in a suitable form for direct introduction into analytical instruments (Tankiewicz et al.‚ 2011). Sample preparation can be thought of as any treatment that the sample is subjected to following its collection‚ prior to its analysis
