Abstract
Surface sampling techniques include thermal desorption, desorption electrospray ionization, low temperature plasma, direct analysis real time, atmospheric pressure matrix assisted laser desorption ionization, are used for explosive detection in a screening system.
Claims5
An system for screening an item for the detection of an explosive agent comprising:
- an automated sample arm capable of being adjustably positioned in close proximity to a surface of an item;
- a thermal desorption and/or desorption ionization surface sampling device coupled to a distal end of the automated sample arm, the surface sampling device configured to release a sample from the item;
- a sample collection device capable of receiving the sample released from the item;
- an explosive detector in fluid communication with the sample collection device, wherein the explosive detector is configured to analyze the sample released from the item for an explosive agent

A surface sampling method for screening an item of mail for an explosive threat comprising:
- (a) positioning an automated sample arm having a thermal desorption and/or a desorption ionization surface sampling device attached thereto in close proximity to a surface of the item of mail;
- (b) activating the surface sampling device thereby causing a sample of analytes to be released from the surface;
- (c) collecting the sample of analytes and conveying the sample of analytes to an explosive detector to analyze the sample;
- (d) analyzing the sample of analytes with the explosive detector to determine the presence of an explosive agent.
