Abstract
Un système de collecte déchantillons de fluide (10) comprend un flacon (12), un piston (66) et un dispositif de collecte déchantillons de fluide (54) comportant un absorbant (64) pour absorber et retenir un échantillon de fluide. Le piston (66) comprend une partie poignée allongée (68) et une partie tête de piston (70) reliée de manière amovible à la partie poignée (68). Il est également doté dun pare-éclaboussures (96) supporté sur la partie poignée (68). Durant le processus de collecte déchantillons, labsorbant saturé (64) provenant du dispositif de collecte déchantillons de fluide (54) est placé dans le flacon (12) et le piston (66) est alors avancé vers une extrémité fermée du flacon (12) pour exprimer léchantillon de fluide de labsorbant (64). La partie tête du piston (70) est retenue dans le flacon (12) avec labsorbant (64) dans un état généralement comprimé et la partie poignée (68) est détachée et retirée du flacon (12).
