General description
Visit our Sensor Applications portal to learn more.
TISAB, in general, is mixed with samples, as it helps in maintaining the ionic strength and pH constant. It is mainly used to decomplex metal-F complexes. TISAB II can be prepared using NaCl with glacial acetic acid, 1,2-Cyclohexylenedinitrilotetraacetic acid and NaOH. It also has high concentrations of cation chelators that hydrolyse fluoride-ion pairs to form fluoride ions.

Application
TISAB II is used to determine total fluoride concentration using fluoride ion-sensitive electrode from dental varnish. It may also be used for the fluoride determination in presence of Fe(III) and Si.
