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.

Famous quotes containing the words total, strength and/or adjustment:
“The word infant derives from Latin words meaning “not yet speaking.” It emphasizes what the child cannot do and reflects the baby’s total dependence on adults. The word toddler, however, demonstrates our change in perspective, for it focuses on the child’s increased mobility and burgeoning independence.”
—Lawrence Kutner (20th century)
“Pater: too much graceful drapery obscures the strength of the body beneath.”
—Mason Cooley (b. 1927)
“The adjustment of reality to the masses and of the masses to reality is a process of unlimited scope, as much for thinking as for perception.”
—Walter Benjamin (1892–1940)
