Les supports pelliculaires continuent, plus que dans les autres méthodes, à présenter un certain intérêt en chromatographie d'échange d'ions, dans la mesure où ils permettent d'obtenir des séparations en des temps d'analyse très courts, en particulier dans le cas d'espèces volumineuses où il est possible d'opérer avec des résines à faible taux de pontage déposées ou greffées sur support inerte, du fait de leur excellente résistance à la pression et de leur bonne efficacité. De plus, ils se prêtent à la technique du remplissage à sec des colonnes. 1, record 1, French, - support%20pelliculaire

Un compromis très satisfaisant entre efficacité maximale et longévité de la colonne chromatographique consiste à remplacer sur 5 mm environ le remplissage du haut de colonne par des microbilles de verre (ou de support pelliculaire de même nature que la phase stationnaire), puis à obstruer la colonne avec un disque en PTFE poreux. 1, record 1, French, - support%20pelliculaire

Matériaux de la séparation chromatographique. [...] on utilise des colonnes capillaires formées d'un tube de métal, de verre, de silice fondue ou de quartz, dont le diamètre intérieur est de l'ordre de 0,2 à 0.5 mm et la longueur de 50 à 100 m, ou davantage. L'adsorbant y est fixé sous forme d'une fine couche collée à la paroi interne du tube [...] (colonnes P.L.O.T.) [...] ou bien la phase stationnaire est fixée en film mince, sans support, sur cette même paroi [...], à moins que l'on préfère une phase stationnaire imprégnant une fine couche de support [...] 1, record 2, French, - colonne%20P%2EL%2EO%2ET%2E
