“…54 These authors prepared stationary phases based on sorption of poly(methyloctylsiloxane) (PMOS) on irregular Davisil silica particles (10 mm), using the method of static evaporation of solvent. In this method, the polymer is dissolved in an organic solvent, in which the polymer is completely soluble and then appropriate quantities of silica are added to this polymer solution with gentle stirring.…”

“…54,55 These new stationary phases were then tested using a mixture (acetone, benzonitrile, benzene, toluene and naphthalene) much used by column manufacturers at that time. This test mixture conveniently evaluates stationary phase selectivity, efficiency and resolution.…”

“…Também são utilizados poliéteres, polissacarídeos, poliaminas, polinucleotídeos, poliamidas e proteínas. Dentre os suportes utilizados na preparação de fases estacionárias com polímeros estão a sílica 13,62,64,[70][71][72][73][84][85][86][87][88][89][90][91] , a zircônia 13,17,70,71,[76][77][78][79][80][81][82][83]92,93 , a titânia 81 e a alumina 14,64,66,74,75,92 . A forma mais simples de preparar o compósito suporte-polímero é pela deposição de uma camada polimérica sobre a superfície do suporte, sem promover a reticulação entre as cadeias do polímero e também sem a ligação química entre o polímero e o suporte.…”

“…As fases estacioná-rias preparadas utilizando este método apresentaram propriedades cromatográficas similares às colunas comerciais recheadas com fases estacionárias contendo os mesmos grupos alquilas [85][86][87][88][89] . Entre os resultados interessantes obtidos nesta pesquisa, um estudo da distribuição do PMOS líquido nos poros, quando os poros não estão cheios, indicou que ela não é uniforme; o líquido encon-(12) (13) tra-se preferencialmente distribuído em gotas ou "plugs" 86 .…”
