DESCRIPTION:
The National Institute for Standards and Technology (NIST), Applied Chemicals and Materials Division (ACMD) is building the infrastructure to advance breathalyzers for law enforcement and clinical diagnosis. Exhaled breath contains volatile organic molecules (VOCs) with the potential to reveal exposure to drugs and toxins, infectious disease, and chronic disease, but determining someone-s “breathprint” requires accurate measurements of molecules with breath concentrations ranging from parts-per-billion (ppb) to parts-per-trillion (ppt). ACMD is developing breath surrogates containing VOCs that span a range of volatilities, chemical characteristics, and concentrations to provide device developers with tools to benchmark the performance of novel breathalyzers. This work requires characterizing the concentration accuracy that can be achieved for VOCs in mixtures whose composition matches the major features of exhaled breath, specifically its temperature, bulk composition, and humidity.
ACMD utilizes gas chromatography with flame ionization detection (GC-FID) to characterize breath surrogates with VOC concentrations at or above 5 parts-per-million (ppm), but an additional preconcentration system is required for breath surrogates with trace VOC concentrations. Systems developed to concentrate VOCs from air samples are most applicable to VOCs in humid breath samples, but there are also some different requirements due to the volatility of the VOCs of interest and the higher relative humidity of breath samples. The two main requirements for this System for Concentrating Trace VOC are that the gas stream (humid air sample) must remain at 20 C or higher during the entire preconcentration process so that higher boilin... - Documents:
