SALD-2300

The particle size distribution of powdered raw materials has a significant impact on the performance of drugs, cosmetics, food, rechargeable batteries, and other finished products, and is an important indicator for quality control. As the demand for particle size measurement expands to various fields, Shimadzu has developed a particle size analyzer that can provide a wider measurement range and facilitate precise measurements efficiently. Its particle size measurement range can reach 17 nanometers to 2500 micrometers. Moreover, by optimizing the optical path and detector, the sensitivity has been increased by 10 times, making it easy to handle samples with concentrations between 0.1ppm and 200000ppm.
In addition, SALD-2300 also adopts a single high-energy semiconductor light source design, which does not require switching the light source during the measurement process. Therefore, its shortest measurement interval is only 1 second and can be continuously measured, allowing for real-time monitoring of particle aggregation or dispersion processes and confirmation of sample state changes. This light source has higher energy and can detect particles with severe light absorption. It also has the advantages of short start-up preheating time and longer lifespan. The newly equipped Wing SALDII series software focuses on solving the problem of laser particle size refractive index selection, and is exclusively equipped with an automatic refractive index selection function. In the past, people used refractive index data provided in literature, but the refractive index was affected by particle size and shape, so this method was not reliable. Shimadzu Corporation has developed for the first time in the world an automatic refractive index selection function based on the LDR principle (light intensity distribution recalculation) in software, which can provide 5 optimal recommended refractive indices based on the particle size data obtained from the sample, and give confidence.
Measurement range: 0.017~2500um Measurement mode: wet or dry

The entire measurement range is continuously covered by a single measurement principle, a single optical system, and a single light source.
Adhering to the single measurement principle, single optical system, and single light source of ISO standards, it covers a particle size range of 17nm (0.017 μ m) to 2500 μ m, achieving continuous single wide range measurement. There will be no data discontinuity or mismatch caused by the combination of multiple light source result data.

Capable of achieving rapid and continuous measurement of samples at 1-second intervals. It can be used to monitor and determine the aggregation process of samples that are prone to aggregation or other unstable particle changes, such as monitoring the antigen antibody reaction process. It can also be used to determine whether the sample has been uniformly dispersed.

Extremely high stability of optical systems.
Adopting an Omnidirectional Shock Absorption Frame (OSAF) structure, all elements of the optical system are protected from interference such as impact and vibration, so there is almost no need to adjust the optical axis. The light source is specially designed for high stability, and since the measurement can be completed in 1 second, even if the light source drifts in abnormal situations, the impact on particle size can be ignored in the ultra short measurement time.

The operation of the sample pool is simple.
Adopting a sliding pool frame makes it easy to replace and clean the pool.

Use AI automatic range function for particle size distribution calculation.
The AI automatic range function is to first determine the particle size distribution range from the detected diffraction/scattering light intensity distribution data, select the most suitable calculation conditions for the obtained range, and accurately calculate the particle size distribution. Therefore, from sharp distributions to wide distributions, the granularity distribution morphology can be accurately obtained without prior information.

Solved the problem of refractive index selection: automatic refractive index selection function.
To determine particle size using laser diffraction scattering method, the refractive index must be selected. In the past, people used refractive index data provided in literature, but the refractive index was affected by particle size and shape, so this method was not reliable. Shimadzu Corporation has developed, for the first time in the world, an automatic refractive index selection function based on the LDR principle (light intensity distribution recalculation) in software. This method has been presented at multiple conferences and named the 'Kinoshita Method'.

By improving the method of calculating granularity distribution, the granularity distribution graph can be represented on the software screen in about 1 second at the fastest. Moreover, it can represent real-time granularity distribution data and light intensity distribution data. Thus, it is possible to monitor the random changes and dispersion state of the sample in real time.

Combined with powerful self checking function, it can confirm the operation status of the device, making maintenance easy.

Equipped with operation log function.
By using the operation log function, all measurement data includes detailed information such as the usage status of the device and the staining status of the pool. Therefore, it can be traced back to the past to verify the authenticity of the measurement data. Although not displayed in normal state, all measurement data are accompanied as text files with the time of power on, the time of blank measurement, and the data of blank measurement, as well as data related to the operation and usage status of the device such as the position of the optical axis at this time.

Multi dimensional evaluation of measurement results: equipped with multiple analytical application methods.
a) Scattering angle evaluation: Provide the relationship between intensity distribution and scattered light angle
b) Data conversion (simulation): The results obtained using other instruments or measurement principles can be simulated through the measurement results of SALD series products. This makes the SALD series results consistent with those obtained using conventional measurement techniques.
c) Mixture simulation function: The particle size distribution results obtained by mixing multiple mixtures in any ratio can be simulated through software. This allows us to accurately obtain the desired particle size distribution results by obtaining the mixing ratio without the need for actual mixing experiments.
d) Data merging: This function combines two different ranges of data at a certain point to obtain an overall granularity distribution result. For example, combining the results of SALD series below 2000um with those obtained through screening method above 2000um yields a wide range of particle size distribution results, which have wide applications in civil engineering, fire prevention, and environmental fields.

The measurement function is linked to the data processing function, allowing for quick data comparison and analysis after measurement.
The measurement function, data processing function, and statistical function are interconnected. Measurement, comparison, and analysis can be performed under the same operation, suitable for up to 200 data points.
