摘要： The invention provides a method and apparatus for efficiently measuring and analyzing volatile and relatively non-volatile flavor components released during oral processing of food or other products. The subject exhales a breath sample into one or more temperature-controlled collection chambers (12), preferably at predetermined time intervals during the oral processing of the product. Each breath sample is then purged from its collection chamber (12) with a non-reactive gas flow into an adsorbent, absorbent or other trap (30) containing an interface that separates and collects the volatile and relatively non-volatile components from the breath sample. The trap (30) is then transferred to a thermal desorber (36) to release the volatile and relatively non-volatile flavor components from the interface surface into a measuring and analysis apparatus (32,34).

摘要： A gas chromatography system featuring column bifurcation and pressure tuning. The system of this invention incorporates a bifurcated system in which samples eluting from a first separation column are directed selectively through one of two or more additional separation columns. Flow directing is achieved through the use of valves which switch carrier gas which are outside of the path of the analyte mixture. Effective tuning of the system is provided by adjusting the intermediate pressure which controls the effective lengths of the initial separation column and the additional final separation columns.

摘要： A detection system and method are disclosed for detecting vapors of specific compounds in air. Vapors such as explosives are stripped from surfaces using heat and suction from a hand-held sample gun (120), are collected on surfaces coated with gas chromatograph material which trap explosives vapors but repel nitric oxide, then are desorbed and concentrated in one or more cold spot concentrators (212, 214). The vapors in hydrogen carrier gas are separated by a high speed gas chromatograph (250), after which specific vapors are decomposed in two pyrolyzers (276, 278) arranged in parallel and the resulting nitric oxide is detected. A low temperature pyrolyzer (278) with silver produces NO from nitramines or nitrite esters; a high temperature pyrolyzer (276) decomposes all explosives vapors to permit detection of the remaining explosives. Also disclosed is a series arrangement of pyrolyzers (352, 354) and gas chromatographs (360, 368) and an NO detector (370) to time-shift detection of certain vapors and facilitate very fast, selective analyses.

摘要： A gas chromatography system of the type incorporating a thermal focusing chamber for introducing a sample into a column for separation and analysis. The system of the present invention provides benefits in terms of reducing memory effect of one analysis being influenced by prior experiments, a reduction in system dead volume which leads to broadening of peaks produced on the chromatogram and artifacts caused by sample decomposition. These advantages are achieved principally through a novel fluid circuit in which the sample is trapped onto the column by trapping it at the end of the thermal focusing chamber closest to the column. This feature has the effect of eliminating the necessity of the sample residing in the heated focusing chamber for a period giving rise to sample decomposition. This system further avoids the necessity of passing the inlet flow through mechanical valves which also contributes to memory effect. This system further has the benefit of enabling sampling of sources at various pressures including ambient pressure as an air quality sensing probe. An alternative embodiment is a simplified system for enabling ambient pressure source monitoring without mechanical valves in the sample flow path.

摘要： Un dispositif et un procédé de détection de vapeurs de composés spécifiques dans l'air font l'objet de l'invention. Des vapeurs telles que des explosifs sont extraites de surfaces utilisant la chaleur et la dépression résultant d'un pistolet d'échantillonnage manuel (120), sont recueillies sur des surfaces revêtues de matière de chromatographie à gaz qui captent les vapeurs des explosifs mais repoussent le bioxyde d'azote, sont ensuite dégagées et concentrées dans un ou plusieurs concentrateurs à point froid (212, 214). Les vapeurs contenues dans le gaz porteur hydrogène sont séparées par un chromatographe à gaz à vitesse élevée (250), après quoi les vapeurs spécifiques sont décomposées dans deux pyrolyseurs (276, 278) disposés parallèlement et le bioxyde d'azote obtenu est détecté. Un pyrolyseur à basse température (278) avec de l'argent produit NO à partir de nitramines ou d'esters nitritiques; un pyrolyseur à température élevée (276) décompose toutes les vapeurs explosives pour permettre de détecter le reste des explosifs. L'invention décrit également une disposition ensérie de pyrolyseurs (352, 354) et de chromatographes à gaz (360, 368) et un détecteur de NO (370) pour la détection à décalage temporel de certaines vapeurs et pour faciliter des analyses sélectives très rapides.
