A method for obtaining 2 soil sample (11) for laboratory analysis of VOC content includes providing a cartridge (113) having an open mouth portion (17) and a proximal end (115). The cartridge (113) is urged into soil to extract a sample (11) while retaining the proximal end (115) seated. The mouth portion (17) is closed, the totatty-seated cartridge (113) is transported to a laboratory and the sample (11) is ejected from the cartridge (113) directly into a laboratory vial (53). A cartridge (113) used in the method has a barrel (13) and an attachment portion (117) coupled to the barrel (13). Such portion (117) permits attaching a removable handle (23a) used to urge the cartridge (113) into the soil surface.

L'invention se rapporte à un procédé conçu pour obtenir un échantillon de terre (11) afin d'analyser en laboratoire sa teneur en composés organiques volatils (COV), et qui consiste à former une cartouche (113) comportant une partie d'admission ouverte (17) et une extrémité proximale (115). On pousse la cartouche (113) dans la terre afin d'extraire un échantillon (11) tout en gardant l'extrémité proximale (115) hermétiquement fermée. On ferme la partie d'admission (17), puis on transporte la cartouche (113) hermétiquement et totalement fermée dans un laboratoire où l'on éjecte l'échantillon (11) de la cartouche (113) pour le placer directement dans un flacon (53). La cartouche (113) utilisée dans ce procédé possède un corps cylindrique (13) et une partie de fixation (117) raccordée au corps cylindrique (13). Cette partie (117) permet de fixer une poignée amovible (23a) utilisée pour pousser la cartouche (113) dans la surface du sol.
