Quantification of six bioactive compounds in Zhenqi Fuzheng preparation by high-performance liquid chromatography couple

A simple and accurate high-performance liquid chromatography（HPLC）coupled with diode array detector（DAD）and evaporative light scattering detector（ELSD）was established for the determination of six bioactive compounds in Zhenqi Fuzheng preparation（ZFP）.The     

车用金属载体催化剂铝溶胶制备试验研究

分别以氯化铝、氧化铝、氢氧化铝和拟薄水铝石为原料制备了铝溶胶,并对铝溶胶的粘接强度和稳定性进行了检测与评价。结果表明,以氯化铝为原料制备的铝溶胶理化特性最好,但容易引入有毒害作用的氯离子;以氧化铝粉和氢氧化铝为原料制备的铝溶胶稳定性和粘接强度不能满足金属载体催化剂涂层的制备要求;以拟薄水铝石为原料制备的铝溶胶不仅能满足金属载体催化剂涂层制备的要求,且不会向催化剂中引入有毒害作用的氯离子,是制备铝溶胶的最佳材料。
