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:
“It is not contrary to reason to prefer the destruction of the whole world to the scratching of my finger. It is not contrary to reason for me to choose my total ruin, to prevent the least uneasiness of an Indian, or person wholly unknown to me. It is as little contrary to reason to prefer even my own acknowledged lesser good to my greater, and have a more ardent affection for the former than the latter.”
—David Hume (1711–1776)
“... there was one of two things I had a right to, liberty, or death; if I could not have one, I would take de oder; for no man should take me alive; I should fight for my liberty as long as my strength lasted, and when de time came for me to go, de Lord would let dem take me.”
—Harriet Tubman (c. 1820–1913)
“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)
