LAB REPORT I: FRACTIONAL DISTILLATION AND GAS CHROMATOGRAPHY INTRODUCTION The purpose of this lab is to investigate the processes that can be used to separate two volatile liquids in a mixture based on their chemical properties.

Gas Chromatography is a process by which a mixture is separated into its constituents by a gas phase moving over a stationary phase. The mobile phase is a carrier gas, usually an inert gas such as helium or an unreactive gas such as nitrogen. In preparative chromatography, GC can be used to prepare pure compounds from a mixture.

Schnell 2 Introduction: Gas chromatography is an analytical separation technique that analyzes compounds eluted from a column, which carried through the column by a gas mobile phase. The carrier gas in our experiment was helium. We used helium gas because it has a thermal conductivity that is higher than any of the analytes we used.

Gas Chromatography Lab Report. Gas Chromatography Guidelines, Handout. Gas chromatography is a technique used to analyze chemical compounds that can be vaporized and separated in a gas phase column. Once separated, the analyzed substance is passed through a detector and data is obtained.

In this experiment we will study the method of gas chromatography. Gas chromatography (GC) is one of the most important analytical tools that the chemist has. In this lab you will watch and listen to a video presentation about GC, look at a research-level GC instrument, and learn how to do a qualitative and quantitative GC analysis. A schematic outline of a typical instrument is shown below.

The experiments performed in this lab were based on Gas chromatography – specifically gas-liquid chromatography. This technique involves a sample being vapourised and injected onto the head of the chromatographic column. The sample is transported through the column by the flow of inert, gaseous mobile phase.

High Performance Liquid Chromatography Lab Report. High Performance Liquid Chromatography or also known as High Performance Liquid Chromatography is one of the most powerful and most commonly used analytical separation technique. HPLC is a form of liquid chromatography that separated solutes/compounds dissolved in the solution (High-performance ...

In the case of gas-liquid chromatography, the column is usually packed with solid particles that are coated with a non-volatile liquid, referred to as the stationary phase. As the sample mixture moves through the column, sample components that interact strongly with the stationary phase spend more time in the stationary phase vs. the moving gas phase and thus require more time to move through the column. For example, a non-polar molecule such as hexane would interact strongly with a non-polar stationary phase and would have a large retention time.

Gas Chromatography Lab Report 1545 Words | 7 Pages INTRODUCTION A gas chromatograph (GC) can be utilized to analyze the contents of a sample quantitatively or in certain circumstances also qualitatively. In the case of preparative chromatography, a pure compound can be extracted from a mixture.
