Mr. Sousa Organic Chemistry ACL 8 January 2015 Chromatography Chromatography is a physical method of separating substances based on their properties‚ by distributing their components between a mobile and stationary phase. Chromatography is useful for observing mixtures and solvents‚ since it can be used to determine the relative bond strength of various compounds‚ a substances phase‚ and it can also the identity of unknown substances. Chromatography allows for the separation of chemical mixtures

Alkenes from Alcohols: Analysis of a Mixture by Gas Chromatography Aim: To analyze a mixture of alkenes by gas chromatography. Introduction: In this lab‚ we specifically used elimination reaction; however we only used the E1 reaction. In the presence of strong acids‚ alcohols protonate to form a good leaving group‚ namely water. Upon loss of a proton to a good leaving group‚ an introduction of unsaturation (a double bond) can be preformed. According to Wikipedia‚ an E2 reaction is typically

Chromatography (Greek for ‘colour writing’) is used to describe various methods applied to separate mixtures (referred to as the sample of the experiment) with great accuracy to analyze them. By using chromatography we can manipulate these to move at different speeds through the system‚ thus separating them. Chromatography is necessary in chemical industries‚ as well as bio processing companies. Chromatography can be: 1. analytical: used to measure ratios of analytes(substance in simpler forms)
