1. Self-Immobilization of Poly(methyltetradecylsiloxane) onto Metalized Silica Particles as Stationary Phases for HPLC
This work presents a study of the sorption of a pre-synthesized polysiloxane, poly(methyltetradecylsiloxane) - PMTDS, onto zirconized and titanized-silica particles that results in efficient stationary phases for reversed phase liquid chromatography. The sorbed materials, after 6 days at room temperature without any chemical or physical agent, denominated as

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

7. Desenvolvimento de fases estacionarias C-8 sorvidos e imobilizadas para CLAE a partir de silica zirconizada
The purpose of this work is the development of stationary phases for Reversed Phase High Performance Liquid Chromatography (RP-HPLC) applications, using zirconized silica as support and the C-8 polymer poly(methyloctylsiloxane)-PMOS as liquid phase . The zirconized silica was synthetized by reaction of 10 mm porous silica with zirconium butoxide. The support
