Complete Particle Characterization from Nanoparticles to Surfaces: One Portfolio, Infinite Possibilities

From nanometer-sized particles to macroscopic surfaces, understanding the physical properties of materials is critical for advanced material science, battery development, pharmaceutical manufacturing, and environmental research. Among these properties, particle size, shape, and zeta potential in particular are central to predicting and controlling behavior in real-world applications.

To meet these requirements, Anton Paar’s particle characterization portfolio delivers precision, flexibility, and reliability across the entire size spectrum, empowering both R&D and quality control teams.

Unlocking shape and size: Dynamic image analysis

For materials where shape influences flowability, compaction, or reactivity, dynamic image analysis (DIA) provides unmatched insight. In lithium-ion battery production, for instance, DIA is used to monitor the transformation of PTFE from spherical particles into fibrous networks during dry mixing. The result: better mechanical stability and enhanced electrode performance.

Anton Paar’s Litesizer DIA series enables real-time analysis of particle size and shape for particles ranging from 0.5 µm to 16,000 µm. With three exchangeable dispersion units – Liquid Flow, Dry Jet, and Free Fall – it ensures optimal performance across sample types, from free-flowing powders to sticky agglomerates.

Fast, robust QC with laser diffraction

When production efficiency is key, laser diffraction offers a rapid, high-throughput solution. In battery quality control, for example, the sizing of LiCoO₂ cathode materials ensures consistent distribution for optimal sintering, packing density, and electrochemical performance.

The Litesizer DIF 500 provides accurate particle size distributions from 0.01 µm to 3.5 mm, with dual-laser technology and broad angle detection from 0.01° to 170°. Built for tough lab environments, it features shock-absorbing components and metal housing for long-term measurement stability.

Nanoparticles and surface charge: DLS, ELS, and streaming potential

The Litesizer DLS combines dynamic and electrophoretic light scattering to assess nanoparticle size and zeta potential, which is key to suspension stability. Carbon black additives in battery slurries, for example, require carefully controlled size and surface charge to balance conductivity and prevent agglomeration.

For solid materials, the SurPASS 3 streaming potential analyzer offers insight into surface charge, isoelectric point, and wettability. It supports a wide range of materials – from pressed powders to membranes – and plays a crucial role in areas such as ceramic-coated separator development for lithium-ion batteries.

One provider, multiple insights

Each solution in Anton Paar’s particle characterization portfolio offers unique strengths. When used together, they provide a complete picture of material behavior, supporting everything from exploratory R&D to inline QC.

From lab bench to production, Anton Paar empowers scientists and engineers to fine-tune materials for better products, safer batteries, and more efficient processes – one particle at a time.
