Title
(EN) WIPE FOR EXPLOSIVES AND NARCOTICS DETECTION
(FR) LINGETTE POUR LA DÉTECTION D'EXPLOSIFS ET DE STUPÉFIANTS
Abstract
(EN)
A wipe for collecting a sample from a surface for analysis in a detector includes a substrate having first and second surfaces. The wipe can have a high-heat tolerant polymeric material on the substrate and a plurality of openings formed in the substrate and polymeric material to form the wipe. The wipe is flexible and conforms to the surface for collecting the sample. The wipe adsorbs the sample from the surface and desorbs the sample in the detector. The wipe is reusable for collecting one or more subsequent samples.

Cette invention concerne une lingette pour collecter un échantillon à partir d'une surface en vue d'une analyse dans un détecteur, comprenant un substrat ayant des première et seconde surfaces. La lingette peut avoir un matériau polymère à haute résistance à la chaleur sur le substrat et une pluralité d'ouvertures formées dans le substrat et le matériau polymère pour former la lingette. La lingette est souple et épouse la surface pour collecter l'échantillon. La lingette adsorbe l'échantillon de la surface et désorbe l'échantillon dans le détecteur. La lingette est réutilisable pour collecter un ou plusieurs échantillons ultérieurs.
