Gas chromatography (GC) is a powerful and widely used tool for the separation, identification and quantitation of components in a mixture. In this technique, a sample is converted to the vapor state and a flowing stream of carrier gas (often helium or nitrogen) sweeps the sample into a thermally-controlled column (see diagram). There are several applications of paper chromatography and other main types of chromatography techniques. This technique is applicable in Pharmaceutical industries, hospitals, forensic science, environmental science and manufacturing plants. This report describes the experiment conducted using paper chromatography to identify an unknown mixture. Chromatography Abstract Paper chromatography is one of the methods under chromatography, it can use in identifying unknown compounds using known compound and it can also use as a separation technique based on the differences in affinities of components of the mixture to a stationary phase and a mobile phase.In the experiment, the stationary phase was the filter paper onto which the dye samples

Experiment 8: Gas Chromatography (GC) In this experiment, mixtures of volatile organic compounds will be separated and analyzed, and a sample containing an unknown percentage of ethanol will be quantitated by GC analysis. In GC, a liquid sample is injected into a separation column as sharp plug.

chromatography, the mobile phase is a gas that carries the analytes through the column and is therefore referred to as the carrier gas. The stationary phase for this experiment is a silicon phase. In this experiment, the carrier gas is inert helium. Just like with a HPLC instrument, a GC is composed of several components. Chromatography serves mainly as a tool for the examination and separation of mixtures of chemical substances. Chromatography is using a flow of solvent or gas to cause the components of a mixture to migrate differently from a narrow starting point in a specific medium, in the case of this experiment, filter paper. 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.

Helium has traditionally been the favoured carrier gas but as laboratory general purpose detector for initial investigations with an unknown sample,  Gas chromatography–mass spectrometry (GC-MS) is an analytical method that combines the features of gas-chromatography and mass spectrometry to identify different substances within a test sample. Applications of GC-MS include drug detection, fire investigation, to less than ten percent of the time required in traditional laboratory systems.
