Realizing precision particle size distribution measurement for undiluted to dilute samples
The key features of centrifugation is that the particle size is measured following classifying by size. As a result, a wide range of high-precision results can be obtained in a single analysis. Partica CENTRIFUGE enables you to measure by two measurement techniques: The “Line-start mode” and the “Homogeneous mode”.

Small amounts of foreign particle or agglomeration can be captured
With its high resolution, Partica CENTRIFUGE can capture a small amount of foreign particles. This instrument enables you to obtain reliable measurement results throughout the range of the particle size distribution, including small populations, as well as to the low area of the distribution.

Features stable measurement even for the long time measurements
The cooling function of the sample chamber and the rotor prevents temperature increases of sample fraction during rotation. This improves the reliability of the measurement results by keeping the viscosity constant. Partica CENTRIFUGE is designed for quieter, easier, safer operation.

Robust and easy to use

•Easy and safe operation by simply setting a cell filled with sample on a rotor.

•The cuvette-type cell is easy to clean and replace, reducing the risk of contamination.

•Complies with international safety standards (IEC6101-1/2-020)


Measurement Examples

High resolution particle size distribution measurement

As a result of measuring a mixed sample containing four types in equal concentrations of, standard silica particles, four types of distributions were obtained with almost the same area. Using the line-start mode measurement, an accurate particle size distribution is obtained because the particles are classified by the centrifugal force.

Sample:  Standard particles (One drop each of particles with sizes of 0.48 μm,
     0.73 μm, 0.99 μm, and 1.57 μm are mixed)
Amount of sample:  10 μL
Solvent:  Aqueous sucrose solution
Measurement condition:  Line-start mode


Measurement of the particle size distribution of a small quantity, high concentration sample

Evaluation of Diameter (Thickness) and Aggregation/Dissociation State of Carbon Nanotube Dispersions
Evaluation of Diameter (Thickness) and Aggregation/Dissociation State of Carbon Nanotube Dispersions
Carbon nanotubes (CNTs) are thin, light, and flexible string-like materials that are composed entirely of carbon atoms. CNTs easily aggregate, so it is essential to understand and control the state of aggregation in order to achieve the expected performance. For this purpose, an analytical method that can quickly evaluate wide particle size distributions (PSD) from isolated dispersion to aggregation, with high resolution, is necessary.
Measurement of Particle Size Distribution of Nanocellulose using Centrifugal Sedimentation Method
Measurement of Particle Size Distribution of Nanocellulose using Centrifugal Sedimentation Method
Nanocellulose is a fibrous material derived from wood that is applied to composite materials and is attracting attention as an advanced material. In order to utilize nanocellulose, it is important to understand the fiber diameter and dispersion state. 3 types of nanocellulose were analyzed using the Partica CENTRIFUGE centrifugal nanoparticle analyzer.
Analysis to Separate Mixed Samples of the Same Size but Different Materials
Analysis to Separate Mixed Samples of the Same Size but Different Materials
In general particle size analyzers, particles of the same size are measured as the same size regardless of material, making it difficult to separate particles of different materials when they are mixed together. The centrifugal sedimentation particle size analyzer measures the sedimentation speed and converts it into a particle size value using the density information of the particles. Therefore, particles of the same size but different densities will have different settling speed and can be measured separately.
Analysis of the Mixed State of Slurry Battery Materials
Analysis of the Mixed State of Slurry Battery Materials
We analyzed two slurry battery materials containing active material (NCM) and conductive agent (carbon). By using Partica CENTRIFUGE to analyze battery materials before and after kneading, results with distinctly different distributions were obtained, which enable us to infer the dispersion state of the battery materials.
High Repeatability Particle Size Distribution Measurement of Colloidal Silica for CMP slurries
High Repeatability Particle Size Distribution Measurement of Colloidal Silica for CMP slurries
CMP technology is essential in the manufacturing process of large scale semiconductor integrated circuits (LSI). Colloidal silica are widely used as CMP slurries because of their clean spherical shape. Colloidal silica was measured by Partica CENTRIFUGE and its measurement repeatability was confirmed.
