New Particle Analysers Measure Both Zeta Potential and Submicron Size

Beckman Coulter, Inc. have launched the Delsa™Nano Series Particle Analysers. The new instruments perform zeta potential and particle size analysis on the same sample. The systems are designed to deliver accurate size measurement on particles ranging from 0.6 nm to 7 µm. The DelsaNano is also designed to measure the zeta potential of concentrated material and solid flat surfaces such as films, paper and glass. It is ideal for any liquid application, including pharmaceuticals, water treatment, paints, paper and petrochemicals.

Beckman Coulter are offering four models in the series – the DelsaNano S for particle size analysis, the DelsaNano Z for zeta potential, the DelsaNano C for both measurements and the DelsaNano HS high-sensitivity instrument for use with concentrated materials and films. An optional Auto Titrator is easily integrated for pH adjustment of the sample.

“We are pleased to offer our customers a single instrument with such flexibility and versatility,” commented Guillermo Smart, product manager for Beckman Coulter. “In addition, all aspects of the system are easy to use.”
