The HORIBA CN-300 centrifugal nanoparticle size analyzer can achieve high-precision measurement of the particle size distribution of undiluted and diluted samples. A single measurement can yield accuracy results over a wide range. The HORIBA CN-300 centrifugal nanoparticle size analyzer can provide two measurement methods: density gradient mode and homogeneous mode.
The particle size is measured after being classified according to the particle size, which is a key feature of the centrifugal separation method. Therefore, a single measurement can yield accurate results over a wide range. The HORIBA CN-300 centrifugal nanoparticle size analyzer can provide two measurement methods: density gradient mode and homogeneous mode.
The HORIBA CN-300 centrifugal nanoparticle size analyzer can capture a small amount of impurity particles due to its high resolution. It enables you to obtain reliable measurement results across the entire particle size distribution range, including those for particle groups with low content and low proportion.
The sample chamber and the turntable have cooling functions, which can prevent the temperature of the sample from rising during rotation. The reliability of the measurement results is enhanced by maintaining the viscosity of the solvent constant. The HORIBA CN-300 centrifugal nanoparticle size analyzer is very quiet and simple and safe to operate.
Just inject the sample into the sample cell
The cuvette type sample cell is easy to clean and replace, reducing the risk of cross-contamination of samples.
The HORIBA CN-300 centrifugal nanoparticle size analyzer is based on the centrifugal separation method. The particle size is derived by measuring the settling velocity of the particles under the action of centrifugal force, thereby obtaining the particle size distribution information. Specifically, the CN-300 center-type nanoparticle size analyzer utilizes the correlation between the settling velocity of particles under the action of centrifugal force and their particle size. By precisely measuring the settling velocity, it deduces the size of the particles and thereby obtains the detailed distribution of particle size .

The sample is injected into a density-gradient solution, and the size of the particles is obtained by calculating the precipitation time required for the particles to reach the detector. This mode enables you to measure very small amounts of high-concentration samples with high resolution.
Centrifugal sedimentation occurs in a uniform sample system, and the particle size distribution is calculated based on the information of particles passing through the detection area. This mode is suitable for measuring low-concentration samples.

The following figure shows the results of a centrifugal particle size analyzer measuring a mixed sample containing four standard silica particles of the same concentration. The areas occupied by the four particles of different sizes are almost the same. Because particles are classified by centrifugal force, using the density gradient mode for measurement can obtain an accurate particle size distribution.
