Portable Contaminant Collector

Contaminants may be collected in the field for return to a central analysis apparatus.

A volatile contaminant is collected for subsequent analysis, by passing it through an absorbent agent contained in a suitable container. For example, ethylvinyl benzene-divinyl benzene polymer (such as commercial "Porapak") may be retained in a glass vial by a porous material such as PYREX* wool. Volatiles collected in this manner are subsequently released from the absorbent by heating the absorbent material, with some means of even heat distribution, while passing inert gas through the container. The heat can be programmed in the range of 23 degrees C to 600 degrees C, and a suitable carrier gas is helium or nitrogen. The gas may be passed through the container in either direction.

The collected products are then analyzed via, for example, a mass chromatograph (which yields the mass numbers of each constituent and a retention time) to identify the products. * Trademark of Corning Glass Works
