Title
(EN) SAMPLE PRECONCENTRATION TUBES WITH SOL-GEL SURFACE COATINGS AND/OR SOL-GEL MONOLITHIC BEDS
(FR) TUBES DE PRECONCENTRATION D'ECHANTILLON A REVETEMENTS DE SURFACE SOL-GEL ET/OU LITS MONOLITHIQUES SOL-GEL
Abstract
(EN) A method of preconcentrating trace analytes is accomplished by extracting polar and non-polar analytes through a sol-gel coating. The sol-gel coating is either disposed on the inner surface of a capillary tube or disposed within the tube as a monolithic bed.
(FR) L'invention concerne un procédé de préconcentration d'analytes traces qui consiste à extraire des analytes polaires et non polaires au moyen d'un revêtement sol-gel. Le revêtement sol-gel est placé soit sur la surface interne d'un tube capillaire, soit à l'intérieur du tube comme lit monolithique.
