碳酸氢钠林格注射液是给予细胞外液补充的液体,主要应用于循环血液量和组织间液减少的情况~([1])。碳酸氢钠林格注射液中的碳酸氢根离子至关重要。碳酸氢根作为一种重要的指标衡量人体的酸碱失衡,因而对碳酸氢根离子的检测有重要意义,当下检测方法数量颇多例如滴定法、电极法等~([2])。其中滴定分析法与抑制型离子色谱法最为常见。本文对两种检测方法进行分析,比较两者的检测效果。1材料与方法 Sodium bicarbonate Ringer injection is given to the fluid extracellular fluid, mainly used in circulating blood volume and interstitial fluid reduction in the situation (1). Bicarbonate in sodium bicarbonate Ringer’s injection is crucial. Bicarbonate is an important indicator to measure the body’s acid-base imbalance, which is of great significance for the detection of bicarbonate ions. The current detection methods such as titration, electrode method, such as the number of ~ ([2]). Which titration and inhibition of ion chromatography is the most common. This paper analyzes the two detection methods to compare the detection results of the two. 1 materials and methods
