Nano Particle Size Analyzer

High-sensitivity Measurement of Nano Particle Size Distribution A powerful new tool for research and development in nanotechnology and life sciences, and for measuring fine bubbles. Evaluation of the dispersion and aggregation characteristics of particles is realized with a wide measurement range and in real time. The SALD-7500nano was developed to provide accurate and high-sensitivity measurement of low concentration or high-light absorption nano particles. It achieves sensitivity in the nano area about ten times higher as compared to conventional instruments. In addition, low concentration...

• Changes in particle size across the 7 nm to 800 pm measurement range can be continuously measured using a single light source, single optical system and single measurement principle. • Since a primary particle and an aggregate and contaminant can be measured with one system, the aggregation properties by a dispersion condition can be checked. Primary particle size Primary particle size The evaluation of the dispersion and aggregation characteristics of the particles is realized with a wide measurement range and in real time. Particle size Particle size • By incorporating a single light source,...

Additionally, because the SALD-7500nano does not incorporate multiple optical systems that create discontinuities in the data, accurate particle size distribution measurements are possible across the entire measurement range...

Laser diffraction method ISO 13320 and JIS Z 8825-1 compliant Tke SALD-7500nano complies with ISO 13320 and JIS Z 8825-1 laser diffraction and scattering standards. Validation possible with JIS standard particles System performances can be confirmed using a MBP1-10 standard particle specified in JIS Z 8900-1. These samples have a broad particle size distribution, which is specified by the JIS standard. Using these samples allows verifying that the instrument is always accurate. Allows verifying the validity of measurement results by referencing light intensity distribution data Since light intensity...

Software Features Eliminates the mistake or trouble of selecting refractive indices Automatic Refractive Index Calculation Function Selecting a refractive index was an unavoidable part of using the laser diffraction method, where generally a published value was entered, but such values were not necessarily appropriate, considering the effects of particle composition and shape. Therefore, tedious trial and error processes were used to select refractive indices. WingSALD II solves such problems by being the world's first software to include a function that automatically calculates an appropriate...

Particle size distribution data and light intensity distribution data can be displayed in real-time This means that changes in the sample over time or shifts in the dispersion status can be monitored in real time. Since both the light intensity distribution data, which is the raw data, and particle size data can be monitored simultaneously, both data sets can be compared to monitor any changes in the status of samples. Updates particle size distributions and light intensity in real time Continuous measurement of 1-second interval particle size changes Normalized Particle Amount (Diff) Changes...

System Structure An evolved nano particle size analyzer for accurate evaluation of nano particles Measurement unit SALD-7500nano Violet semiconductor laser (wavelength: 405 nm) is used for the light source. Maintenance, such as gas replacement, is unnecessary. The detector incorporates 78 elements at the front, 1 element at the side, and 5 elements at the back for a total of 84 elements. Additionally, high-sensitivity light receptors that support violet semiconductor laser wavelengths are adopted with all detectors. The fixed parts of the cell and cell holder can be pulled out at the front of...

System Structure Easy Measurement under PC Control Sampler SALD-MS75 Groups of particles are dispersed in a liquid medium and measured as they are circulated between the flow cell, which is placed in the measurement unit, and a dispersion bath in the sampler. The dispersion bath incorporates a stirrer and an ultrasonic sonicator. A pump delivers the dispersed suspension to the flow cell. The pump is specially designed to ensure both liquid medium and the particles are circulated. It can be controlled from a PC. Most organic solvents can be used as dispersion media. Solvent Resistance Solvent...

Measurement Samples without Dilution High-Concentration Measurement Unit: SALD-HC75 High-concentration samples can be measured using the laser diffraction method. Measurement is possible by simply holding the high-concentration sample particles to be measured between two glass slides. Samples for which the particle size distribution would be changed by dilution can be measured in their original state, or with the minimum required level of dilution, and a true image of the measurement object can be obtained. Commercial hand creams, face creams, and rinses can be measured with hardly any pretreatment....
