This invention describes a sample collection method that could release and collect residues of explosives and other chemicals from a surface; the described method is implemented into a compact detection system that can be used as a “wand” for screening chemicals residues on a subject. The wand configuration includes multi-function for sampling and detecting multiple threads. The invention further describes a method of inspecting a subject using an interrogating apparatus in a sweeping motion; the near range closed loop particle sampling arrangement allows effective collection of particle and vapor residues from a targeted surface. The invention also describes a sampling and detecting apparatus for on-the-fly threat detection using compact ion mobility based detectors.

What is claimed is: 1. A non-contact handheld multi-function interrogating apparatus comprising:(a) a handle that is connected to a front sampling region that comprises a particle sampling component and a metal detector in the same physical location of the front sampling region;(b) the particle sampling component is for actively collecting sample from a threat by searching an object without direct contact; and(c) the metal detector is for simultaneously searching metal objects while collecting sample of the first threat.
