摘要
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 human body. The wand configuration includes multiple functionalities for contrabands detection. The invention further describes a desorption method that can control chemical fragmentation pathway during desorption. The invention describes a combined detection device that detects trace chemicals and metal at the same time.
