Agilent 7020 ZetaProbe Titania Coating QC Application Note

About this manual

Commercial titania particles are often coated with substances like silica or alumina to prevent photoactive breakdown. The Agilent 7020 ZetaProbe is an ideal tool for quality control labs to detect batch-to-batch variability in these surface coatings. The instrument determines the isoelectric point (IEP) by plotting zeta potential against pH, which clearly indicates the type and integrity of the coating.

Frequently asked questions

What is the Agilent 7020 ZetaProbe used for in titania manufacturing?

It is used to monitor the type and integrity of surface coatings on titania particles to detect batch-to-batch variability.

How quickly can the ZetaProbe determine the isoelectric point?

The instrument can determine the isoelectric point to better than 0.1 pH units in under half an hour.

Does the ZetaProbe require sample dilution for measurements?

No, it does not require sample dilution because it uses a patented electroacoustic technique for concentrated suspensions.
