NanoCoulter™ is an expert in single particle characterization.

Wider particle size range: 50 - 2000 nm

Single-particle zeta potential measurement

Unparalleled Detection Performance

Simultaneous single-particle size and zeta potential measurement.

Zeta potential is an important indicator of the stability of dispersion systems. Under a constant electric field, the speed at which particles move is positively correlated with the absolute value of the Zeta potential. NanoCoulter measures the time it takes for particles to pass through a nanopore to obtain Zeta potential data, making it the only technology platform capable of simultaneously measuring single-particle size, Zeta potential, and concentration.

PDI vs. SPAN: Which Metric Best Represents Particle Size Distribution?

June 13, 2025

In the fields of nanotechnology and materials science, particle size distribution (PSD) is a critical parameter that directly influences the performance and applicability of nanomaterials. Two of the most commonly used indicators to evaluate PSD are the Polydispersity Index (PDI) and the SPAN value. While often used interchangeably, these two metrics differ significantly in how they are calculated and interpreted. Understanding the distinction between PDI and SPAN is essential for accurate particle characterization.
