中文百科

总离子强度调节缓冲溶液

总离子强度调节缓冲溶液TISABTotal Ionic Strength Adjustment Buffer)是一种用于保持溶液具有较高的离子强度的缓冲溶液。通常来说,这种溶液主要应用在电位分析法上,尤其是与离子选择性电极有关的电位分析。由于在电位分析法中的电位值往往与被分析离子的活度(而不是浓度)的对数成线性关系,总离子强度调节缓冲溶液对于分析的准确度有着至关重要的意义。

英语百科

Total ionic strength adjustment buffer 总离子强度调节缓冲溶液

A total ionic strength adjustment buffer (TISAB) is a buffer solution which increases the ionic strength of a solution to a relatively high level. This is important for potentiometric measurements, including ion selective electrodes, because they measure the activity of the analyte rather than its concentration. TISAB essentially masks most chemical interferences in the analyte solution and hence increases the accuracy of the reading.
