Title
(EN) METHOD OF TRACE SAMPLING
(FR) PROCÉDÉ D'ÉCHANTILLONNAGE DE TRACE
Abstract
(EN)
A method of sampling for trace substances and apparatus for the same. An item to be sampled is placed in an item holder (20), the item holder (20) comprising retention means (21) (optionally a frame) for holding the item, and adjustment means (22) for positioning and orientating retention means (21). The retention means (21) is orientated to a predetermined orientation using the adjustment means (22). The item within the item holder (20) is then sampled using sampling apparatus (25) (optionally a swab). This improves the repeatability of sampling, particularly for direct sampling methods and apparatus used in security screening.
(FR)
L'invention concerne un procédé d'échantillonnage de substances à l'état de trace et un appareil associé. Un objet à échantillonner est placé dans un support d'article (20), le support d'article (20) comprenant un moyen de retenue (21) (éventuellement un bâti) servant à maintenir l'article, et un moyen de réglage (22) servant à positionner et à orienter le moyen de retenue (21). Le moyen de retenue (21) est orienté dans une orientation prédéfinie à l'aide du moyen de réglage (22). L'article à l'intérieur du support d'article (20) est ensuite échantillonné à l'aide d'un appareil d'échantillonnage (25) (éventuellement un écouvillon). Ceci améliore la répétabilité de l'échantillonnage, en particulier pour des procédés et un appareil d'échantillonnage direct servant à un criblage de sécurité.
