<p>Air or gas is drawn into a particle impact collector where the air or gas is forced through non-linear passages inside the collector in such a manner that particles or droplets entrained in the air or gas, or contaminant vapors in the air or gas, are retained in and concentrated by the passages. Once retained and concentrated, the contaminants are suspended or dissolved in a liquid collection medium purging the passages, the collection medium containing assay reagents for a multiplexed binding assay. The agitation produced by the flow of gas and liquid through the non-linear passages increases the reaction rate of the assay.</p> |
