实现对未稀释和稀释样品粒径分布的精确测量
颗粒的粒度是按粒径大小分类后测量的,这是离心分离法的关键特点。因此,一次测量就能得到宽范围内的高精度结果。CN-300可提供两种测量方法:“密度梯度模式”和均一模式”。

可捕捉到少量杂质颗粒或团聚体
CN-300因其高分辨率可以捕获到少量的杂质颗粒。它能让你在全粒径分布范围内获得可靠的测量结果,包括含量少占比低的颗粒群。

仪器在长时间测量后性能依然稳定
样品室和转盘具有冷却功能,可防止样品在旋转过程中温度升高。通过保持溶剂的粘度恒定提高测量结果的可靠性。CN-300更安静,操作更简单安全。

坚固耐用易操作

• 仅需将样品注入样品池

• 比色皿式样品池易清洁、易更换,减少样品交叉污染的风险。

• 符合国际安全标准 (IEC6101-1/2-020)


测量案例

高分辨率测量粒径分布 

下图为离心粒度分析仪测量含有四种相同浓度的二氧化硅标准颗粒的混合样品的结果,四种不同粒径颗粒所占面积几乎相同。因为颗粒按离心力分类,使用密度梯度模式测量可以获得准确的粒度分布。

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.
