本工作描述了六个固定相的制备和表征的高效液相色谱(HPLC)通过沉积聚(二甲基硅氧烷)(PDMS)在HPLC二氧化硅颗粒,然后通过固定使用不同的过程(热处理,热处理+微波辐射,自固定+ γ辐射和自固定+微波辐射)。用具有不同性质(酸性、碱性和中性)的供试化合物混合物评价所有相的色谱参数。在高温下使用的中性移动的相和较高pH值的移动的相中评价了这些相之一的稳定性,结果令人满意。
This work describes the preparation and characterization of six stationary phases for high-performance liquid chromatography (HPLC) obtained by deposition of poly(dimethylsiloxane) (PDMS) in HPLC silica particles, followed by immobilization using different processes (thermal treatments, thermal treatment+microwave irradiation, self-immobilization+gamma irradiation and self-immobilization+microwave irradiation). The chromatographic parameters of all the phases were evaluated with a mixture of test compounds having varied natures (acid, basic and neutral). The stability of one of these phases was evaluated in both a neutral mobile phase and a higher pH mobile phase used at an elevated temperature, with promising results.
