General description

We are committed to bringing you Greener Alternative Products, which belong to one of the four categories of greener alternatives. Phosphoric acid-doped polybenzimidazole (PBI) membranes offer a cleaner path to energy by enabling high-temperature fuel cells that efficiently convert hydrogen into electricity with low emissions. Their durability and proton conductivity make them ideal for sustainable power systems. Click here for more information.

Application


  • Development of green micellar HPLC-DAD method for simultaneous determination of some sulbactam combinations used in COVID-19 regimen: 本研究提出了一种利用胶束高效液相色谱和二极管阵列检测 (HPLC-DAD) 的绿色分析方法。该方法专用于同时测定 COVID-19 治疗方案中的舒巴坦和其他化合物,证明了正磷酸在调节流动相 pH 值以提高分析性能和分离效率方面的应用价值(Ragab GH, Saleh HM, Abdulla NM, Bahgat EA, 2023)。
