By a News Reporter-Staff News Editor at Biotech Week -- Investigators discuss new findings in Biotechnology. According to news reporting originating in Toyohashi, Japan, by NewsRx journalists, research stated, "A novel needle-type sample preparation device was developed for the determination of very volatile organic compounds (VVOCs) in gaseous samples by gas chromatography-mass spectrometry (GC-MS). Two types of activated-carbon-based sorbents, Carbopack X and a carbon molecular sieve (CMS), were investigated as the extraction medium."
The news reporters obtained a quote from the research from the Toyohashi University of Technology, "A double-bed-type extraction needle showed successful extraction and desorption performance for all investigated VVOCs, including acetaldehyde, isoprene, pentane, acetone, and ethanol. Sensitive and reliable determination of VVOCs was achieved by systematically optimizing several desorption conditions. In addition, the effects of sample humidity on the extraction and desorption of analytes were investigated with the needle-type extraction devices. Only the CMS packed extraction needle was adversely affected by sample humidity during the desorption process; on the other hand the double-bed-type extraction needle was unaffected by sample humidity."
According to the news reporters, the research concluded: "Finally, the developed double-bed-type extraction needle was successfully applied to the analysis of breath VVOCs of healthy subjects."
