Volatile Organic Compounds: Organic compounds that have a relatively high Vapor pressure at room temperature.

Gas Chromatography (GC) with Flame-Ionization Detection

JoVE 10187

Source: Laboratory of Dr. B. Jill Venton - University of Virginia


Gas chromatography (GC) is used to separate and detect small molecular weight compounds in the gas phase. The sample is either a gas or a liquid that is vaporized in the injection port. Typically, the compounds analyzed are less than 1,000 Da, because it is difficult to…

Measuring Tropospheric Ozone

JoVE 10024

Source: Laboratories of Margaret Workman and Kimberly Frye - Depaul University


Ozone is a form of elemental oxygen (O3), a molecule of three oxygen atoms bonded in a structure that is highly reactive as an oxidizing agent. Ozone occurs in both the stratosphere and the troposphere levels of the atmosphere. When in the stratosphere (located…
