초록

A method for collectively sampling a plurality of cargo items for contaminants such as chemical residues. The items are placed in a generally airtight chamber and agitated physically to release particulates and vapors from the surfaces and interior of the items. The methods of physical agitation include vibrating the items, and pressurizing and depressurizing the chamber, with the pressurizing being done by introducing bursts of high pressure air into the chamber and by directing jets of high pressure air at the cargo. Optionally, the high pressure air m...

청구항

[ What is claimed is:] [1.] A method for sampling surfaces and interiors of a plurality of items for contaminant particulates and contaminant vapors, comprising the steps of:(a) sealing the items inside a chamber containing air;(b) vibrating the items directly, thereby releasing the particulates and the vapors from the surfaces and the interiors of the items into said air; and(c) inducing a flow of said air, together with the released particulates and vapors, towards a collection system, by introducing bursts of said air into said chamber.
