Research focuses on developing analytical methods for accurate generation and verification of trace chemicals in air both individually and in complex mixtures. Novel methods are being explored to create stable and reproducible concentrations of hazardous chemical at parts per trillion to parts per million levels in air. The air will be used to evaluate the performance of new sensors or detection systems. New sample chambers are being designed, modeled, and tested to ensure controlled fluid flow across the systems. Finally, new methods to validate the air stream are being explored using gas chromatography/mass spectrometry and spectroscopy. All of these features are being combined in an automated tested.
