(FR) MEMBRANES COMPOSITES POUR EXTRACTIONS ET REACTIONS EN PHASE SOLIDE
Abstract: front page image
(EN)A solid phase extraction or chromatographic medium comprises a porous nonwoven fibrous matrix comprising at least one of polytetrafluoroethylene and blown microfibers, and sorptive or reactive hydrophobic siliceous molecular sieve particulates enmashed in said matrix, the ratio of molecular sieves to matrix being in the range of 40:1 to 1:40.
(FR)Un support d'extraction en phase solide ou de chromatographie se compose d'une matrice poreuse en fibres non tissées comprenant des microfibres de polytétrafluoroéthylène ou obtenues par soufflage, et des particules adsorbantes ou réactives formant un tamis moléculaire en silice hydrophobe, imbriquées dans ladite matrice, le rapport entre les tamis moléculaires et la matrice se situant dans la plage comprise entre 40:1 et 1:40.
