PHILADELPHIA, March 28, 2013 — The DelsaMax family of particle analyzers from Beckman Coulter Life Sciences measures the size and zeta potential of nanoparticles with speed and high precision using two independent detection systems that operate in parallel — a configuration that streamlines workflows in biological, chemical, material and polymer science applications.
The DelsaMax Pro light scattering and zeta potential analyzer measures the size, structure and charge of particles 0.4 to 10,000 nm in diameter in as little as 1 s. An avalanche photodiode detector provides size measurements, and 31 independent photodetectors measure zeta potential, reducing analysis time and increasing accuracy.
The Pro’s fast, reliable measurement of sub-10 nm particles, weak scatters and dilute systems makes it suitable for chemistry and materials applications. Small biologicals can be analyzed in particles down to 1 nm, and proteins in native conditions are not damaged, allowing stable and reproducible assessment of zeta potential and isoelectric point at low volumes and concentrations.
The DelsaMax Core analyzers use 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 1 µL. The cuvette-based system operates at temperatures between –15 and 150 ºC.
The DelsaMax Assist cell pressurization system forces inert gas into the flow cell of the Pro to reduce bubbling, to stabilize the sample and to simplify injections. The Pro also can connect to a standard high-performance liquid chromatography (HPLC) autosampler to speed sample loading and unloading.
DelsaMax Analysis Software features an intuitive interface with fully customizable autocorrection analysis and the ability to create overlays, custom user variables, reports and more. Spurious data can be edited out without rerunning the sample.
