Abstract
A method and system for sampling high vapor pressure substances is provided. In one embodiment, a sample is pre-concentrated by compression and condensation, water is removed by a condensing gas dryer, particulates are removed from the sample with an electrostatic precipitator; and the sample is shuttled through a sintered core at high vapor pressure so that molecules are condensed on the surface of the sintered core. In another embodiment, a system for sampling high vapor pressure substances includes a shuttle having a first piston and second piston for shuttling a sample through a sintered core at high vapor pressure and a condensing heat exchanger between the first piston and the second piston, the condensing heat exchanger including the sintered core.
