Description:
The research program surveyed and evaluated the methods and procedures used to identify and quantitate chemical constituents in human breath. Methods have been evaluated to determine their ease and rapidity, as well as cost, accuracy, and precision. During the evaluation, a second goal was to determine the feasibility of correlating a preferred method with easily identifiable chemical and physical characteristics of the analyte. To accomplish the goals, an extensive literature review was performed. The information retrieved was summarized and classified by sampling and analysis methodology. The sampling methods found include apnea collection, breathing value, cryogenic trapping, Tenax cartridge and cascade impactors. Analytical methods found are gas chromatography, mass spectroscopy and PIXE.
