血液保养液在医院普遍用于输血的血液抗凝剂。陕西制剂规范规定用离子交换法测定枸橼酸钠含量,因测定所需时间太长,而使制剂的生产时间也延长。曾报道采用电位法、改进的中和法等,但终点不好掌握,误差较大。本法为非水滴定法,排除了制剂中葡萄糖不易干燥的现象,具有准确、快速、不需特殊设备的优点。获得了满意的结果。 Blood maintenance fluid is commonly used in hospitals for transfusion of blood anticoagulants. Shaanxi preparation specification provides ion exchange method for the determination of sodium citrate content, due to the determination of the time required for too long, and the preparation of the production time is also extended. It has been reported using the potential method, improved neutralization method, but the end is not good grasp, the error is larger. This method is non-aqueous titration method, eliminating the phenomenon of glucose in the preparation is not easy to dry, with accurate, fast, without special equipment advantages. Satisfied with the results.
