METHOD AND APPARATUS FOR ON-LINE MONITORING OF VOLATILES TO ANALYSIS USING A MULTI-PORT VALVE AND CRYO-MODULATION

摘要

The present invention is related to a sampling technique for volatiles and its use to concentrate and/or detect and/or separate chemical components of complex mixtures thereof that enable the automatic on-line sampling and real-time analysis of volatiles present at low concentrations, for example in the headspace. The method and apparatus according to the invention comprise loading means equipped with a multiport-valve and mobile cryo-modulation means.
