Beckman Coulter Life Sciences Introduces the DelsaMax Family of Products, Nanoparticle Research Breakthrough at Pittcon

Speed and Precision Increased in Biological, Chemical and Industrial Applications


DelsaMax particle analyzers measure the size and zeta potential of nanoparticles with groundbreaking speed and high precision.  Instruments in the family utilize two independent detection systems that operate in parallel – a configuration that significantly streamlines workflows in biological, chemical, material and polymer science applications.   

DelsaMax PRO light scattering and zeta potential analyzer provides precise measurement of the size, structure and charge of particles 0.4 to 10,000 nm in diameter in as little as one second, the fastest particle analysis available. An Avalanche photodiode detector provides size measurements, and 31 independent photodetectors measure zeta potential, dramatically reducing analysis time and increasing accuracy.

Chemistry and materials applications are facilitated in the PRO through fast, reliable measurement of sub-10 nm particles, weak scatters and dilute systems.  Measuring zeta potential in particles down to 1 nm means that small biologicals can be analyzed, and, importantly, proteins in native conditions are not damaged, allowing stable and reproducible assessment of zeta potential and isoelectric point even at very low volumes and low concentrations.

DelsaMax CORE analyzers utilize independent dynamic and true static light-scattering detectors to measure the size and molecular weight of particles from 0.4 to 10,000 nm, at sample volumes as low as 1µL. The cuvette-based system operates at temperatures between -15º and 150º C.

A unique cell pressurization system, DelsaMax ASSIST, forces inert gas into the flow cell of the PRO to reduce bubbling, stabilize the sample and simplify injections.  The PRO can also connect to a standard HPLC autosampler to speed sample loading and unloading.

DelsaMax Analysis Software features an intuitive interface with fully customizable auto-correction analysis and the ability to create overlays, custom user variables, reports and more. Spurious data can be edited out without rerunning the sample.

“DelsaMax instruments represent a meaningful advance for the measurement of nanoparticles and zeta potential,” said Matt Rhyner, Ph.D., particle characterization global business manager for Beckman Coulter Life Sciences. “Researchers will find that two independent detection systems working in parallel provide fast, detailed analysis and that sophisticated yet accessible innovations in software will make their work as efficient as possible.”
