阅读说明：本技术 用于制备液体混合物的方法 (Method for preparing a liquid mixture ) 是由 E.卡雷德达诺 E.斯特兰德伯格 于 2014-09-26 设计创作，主要内容包括：本发明涉及一种不使用pH计制备具有预定pH值的液体混合物的方法,该方法包括添加和减少控制量的缓冲剂组分,优选呈液体形式,至所述液体混合物；和当获得比电导率值时停止添加和减少缓冲剂组分,其中缓冲剂组分的减少和添加以维持缓冲剂浓度不变的方式进行并且其中所述比电导率值对应于所述液体的预定pH值,并且其中所述比电导率值通过数学模型与所述预定pH值和缓冲剂浓度相关。所述数学模型是表面模型方程,其形式为pH=A+B*浓度+C*浓度^2+D*电导率或pH=A+B*浓度+C*浓度^2+D*电导率+E*电导率^2,其中A、B和C和D和E是缓冲剂系统具体的常数。(The present invention relates to a method of preparing a liquid mixture having a predetermined pH value without the use of a pH meter, the method comprising adding and reducing a controlled amount of a buffer component, preferably in liquid form, to the liquid mixture; and stopping adding and reducing the buffer component when a specific conductivity value is obtained, wherein the reducing and adding of the buffer component is performed in a manner that maintains the buffer concentration constant and wherein the specific conductivity value corresponds to a predetermined pH value of the liquid, and wherein the specific conductivity value is related to the predetermined pH value and the buffer concentration by a mathematical model. The mathematical model is a surface model equation in the form of pH = a + B concentration + C concentration ^2+ D conductivity or pH = a + B concentration + C concentration ^2+ D conductivity + E conductivity ^2, where A, B and C and D and E are constants specific to the buffer system.)
