Tamponi di regolazione di forza ionica
I tamponi di regolazione della forza ionica totale (TISAB) sono soluzioni tampone che aumentano la forza ionica di una soluzione a un livello relativamente elevato. Questo è importante per le misurazioni potenziometriche, inclusi gli elettrodi ionoselettivi, poiché misurano l'attività dell'analita piuttosto che la sua concentrazione. I TISAB sono molto comunemente applicati all'analisi degli ioni fluoruro, come negli elettrodi ionoselettivi per fluoruro. Ogni componente dei TISAB svolge un ruolo importante nel controllo della forza ionica e del pH della soluzione dell'analita.

ISE sample conditioning buffers and solutions
Supplier: WTW
Ion strength adjustment solutions have multiple tasks: TISAB for fluoride measurements does not only adjust the pH value, by also decomplexes the fluoride-containing complex compounds. Other ion strength adjustment solutions ensure an adapted pH value as well as the addition of a suitable conducting salt to correctly capture the concentration.
