Abstract:

The use of infrared spectroscopy in trace analysis can be greatly aided by employing preconcentration and/or separation techniques for appropriate samples. In some cases, classical infrared difference spectroscopy or computer treatment of data will be sufficient to identify qualitatively or to quantitate a trace component in a complex mixture. Analysis of aromatic isomers, gasoline additives, drugs, and polymer additives will be described to illustrate the methods.
