Concentration and analysis of trace volatile organics in gases and biological fluids with a new solid adsorbent

摘要: A new procedure for sampling, transfer, and analysis of volatile organic compounds by gas chromatography has been developed. An adsorbent trap ultimately becomes an insert a modified injector port, valve system allows the sample to be transferred cooled precolumn finally separating column. Several traps may used sampling (for multiple injections), it established that such stored without loss sample. The ease reproducibility this is amenable investigation involving air water pollution, flavor, aroma analyses, body fluid metabolites.
