1. Preparação, caracterização e aplicação de fases estacionárias tipo C8 modificadas por óxidos metálicos para cromatografia líquida
This work describes three C8-stationary phases for high performance liquid chromatography based on silica metallized with ZrO2, TiO2 or Al2O3 layers, having poly(methyloctylsiloxane) immobilized onto their surfaces. The stationary phases were characterized using XRF, XAS, FTIR, SEM and elemental analysis to determine the physical characteristics of the oxide

2. Preparo, caracterização e aplicação de fases estacionárias de poli(dimetilsiloxano-co-metilfenilsiloxano) sorvidas e imobilizadas sobre sílica e sílica zirconizada / Preparation, characterization and application of stationary phases based on poly(dimethylsiloxane-co-methylphenylsiloxane), sorbed and immobilized onto silica and zirconized silica
This work describes the development of new stationary phases (SP) based on poly(dimethylsiloxane-co-methylphenylsiloxane) sorbed and immobilized onto silica and zirconized silica for reversed phase high performance liquid chromatography. The polymer was immobilized by thermal treatment at 140 °C during 6 h, which were the conditions that produced SP with th

3. Desenvolvimento de fases estacionarias para cromatografia liquida de alta eficiencia em fase reversa a partir da adsorção e imobilização do poli(metiltetradecilsiloxano) sobre silica metalizada / Development of stationary phases for reservesed-phase hight-performance liquid chromatography by adsortion and immobilization of poly(metyltetradecysiloxane) onto metalized silica supports
This work presents the development of stationary phases for used in Reversed-Phase High-Performance Liquid Chromatography (RP-HPLC) by sorption and immobilization of poly(methyltetradecylsiloxane) (PMTDS) onto metalized (zirconized and titanized) silica supports. The preparation of metalized silica supports was optimized using experimental design. Two immobi
