The BI-ZTU,
a new autotitrator acccessory designed specifically
for the Brookhaven ZetaPlus and ZetaPALS zeta
potential analyzers, is ideal for automatic determination
of electrophoretic mobility, zeta potentials and
the isoelectric point (IEP) of colloidal materials
and nanoparticles.
Four separate pumps provide unparalled flexibility
for optimizing reagent dosage. For example, dilute
acid and base can be used for precise mid-range
pH control while higher concentrations are used
to speed adjustment at either end of the range.
The overall pH range is from pH 2 to pH 12.
The BI-ZTU can be used to evaluate the effect
on zeta potential of ionic strength or concentration
of surfactants and other additives thus enabling
processes and product performance to be optimised
while using minimum quantities of possibly expensive
chemicals.
An
example of a pH titration measurement in which
data were collected and analysed completely automatically
thereby saving labour and time
