Abstract

L'invention concerne un dispositif d'échantillonnage de liquides organiques qui comprend un support (216) pourvu d'une ouverture (218) prévu pour recevoir l'échantillon de liquide organique, et d'un couvercle (15). Une bande d'essai (200) est comprimée entre le support (216) et le couvercle (15) pour former un coussin en relief (221) avec l'ouverture (218). Le coussin en relief (221) est conçu pour absorber l'échantillon de liquides organiques. La bande d'essai (200) est pourvue d'une entaille qui entoure le coussin en relief (221) et qui permet de réduire les fuites d'échantillons de liquides organiques du coussin en relief (221). Le support (216) peut également comprendre une lame (220) qui entoure l'ouverture (218) et qui sert à former l'entaille autour du coussin en relief (221).
