Experiment 5 Lab Report

Determination of Toluene By Gas Chromatographic Method

Module Name: Fundamental Analytical Chemistry (Practical Section)

Date of experiment: 16/10/2007

Introduction:

Gas chromatography is a specifically gas-liquid chromatography that involves a sample being vaporized and injected onto the head of the chromatographic column. The sample is transported through the column by the flow of inert, gaseous mobile phase, which is usually an inert gas such as helium or an unreactive gas such as nitrogen. The column itself contains a liquid stationary phase, which is a microscopic layer of liquid or polymer on an inert solid support, inside glass or metal tubing that is adsorbed onto the surface of an inert solid. The instrument used to perform gas chromatographic separations is called a gas chromatograph.

A gas chromatograph is a chemical analysis instrument for separating chemicals in a complex sample. A gas chromatograph uses a flow-through narrow tube known as the column, through which different chemical constituents of a sample pass in a gas stream (carrier gas, mobile phase) at different rates depending on their various chemical and physical properties and their interaction with a specific column filling,
