Paper Abstract

Solid phase extraction (SPE) media are usually used to collect samples from both the air and water for analysis by conventional analytical instruments such as the gas chromatograph or mass spectrometer. This approach requires that the analyte be sorbed onto the SPE media, then removed using either solvent extraction or thermal desorption of the vapor into an analytical instrument. Because the analyte is concentrated on the sorbent medium it is possible to acquire spectroscopic information of the analyte on the sorbent. This approach can be used to enhance the detection limits for both Raman and infrared spectroscopic techniques.
