Sam Christy Lab Partners: J. Googins, T. Dunn TA: He Li 12/11/07 FTIR Analysis of Greenhouse Gases Introduction: Earths atmosphere consists of pollutants such as nitrogen oxides, hydrocarbons, carbon monoxide, ozone, and sulfur dioxide. These gases undergo a variety of oxidation and reduction actions; chemists are able to monitor their effects on the atmosphere using a technique known as infrared spectroscopy. The goal of the lab was to understand how certain gases in the atmosphere contribute to the greenhouse effect. Procedures: To begin, take five polyethylene bags. The first bag is going to be filled with nitrogen gas so that it can be used as the blank. Next prepare a carbon dioxide sample by placing a piece of dry ice into the bag and squeezing the rest of the air out of the bag. Tie the bag off and let the carbon dioxide fill the bag as the dry ice melts. The next sample that needs to be prepared is water vapor. Add 1 mL of water to the bag, remove all air inside, and fill with nitrogen gas and tie off. For the next bag fill with atmosphere.
