STUDYING THE EFFECT OF pH ON ZETA POTENTIAL

A new application note describes how the BI-ZTU autotitrator in conjunction with a NanoBrook Series instrument can be used to study the effect of pH on Zeta potential. This system can be set up to titrate within a user-defined pH range, or additively, and produce aggregation data for particle size or zeta potential as a function of pH, or additive concentration.

MONITORING HPLC PUMP PERFORMANCE

HPLC separations have one detail in common: they are reliant on a stable and constant flow rate of solvent and by this they all require constant HPLC pump performance. A new technical report describes the shortfalls of traditional flow measurement techniques and demonstrates how a novel method of continuous monitoring of flow rate can provide real-time validation of the total HPLC system performance and as such, improve reliability of results.
