Abstract

Procédés et systèmes pour déterminer la présence d'un ou plusieurs analytes dans divers types de matrices tels qu'aliments, huiles, fluides corporels, etc. On utilise des membranes pour évacuer des matières étrangères telles que des particules solides et/ou pour lier des interférants ou analytes spécifiques. Des dosages spécifiques servent à déterminer l'acide citrique, les lipides totaux (ou le % de graisse), les acides gras libres, la teneur en protéines ou en acides spécifiques indiquant la présence d'ADN ou d'ARN de certains microbes (tels que les pathogènes) ou de substances génétiquement modifiées (telles que les graines obtenues par génie génétique).
