This page lists applications using SALD-7100. Check out this page from time to time since Dr. Powder is updated on an irregular basis.

1. Evaluation of Aggregation of Vaccines and Proteins
The SALD-7100 Nanoparticle Size Analyzer was developed around of concept of measuring "changes" in particle size distribution. Adoption of a UV semiconductor laser with a wavelength of 375 nm achieves seamless and realtime measurements in the 10 nm to 300 µm measuring range...


2. Measurement of Diameter of Micro-bubbles and Nano-bubbles
In recent years, air bubbles called "Micro-bubbles" and "Nano-bubbles" are expected to be applied in a variety of fields and purposes. However, there is still a lot unknown regarding their actual properties and characteristics. Air bubble size is one of such unknown factors. If the SALD-7100 Nanoparticle Size Analyzer is used, measurement and observation that has not been possible up till now...


3. Evaluation of Particle Dissolution Process
The phenomenon of particle dissolution is a very commonplace phenomenon that occurs on a daily basis at various locations. Yet, in the dissolution process, how the particle size distribution (particle size) changes hardly seems to be quantitatively observed...


4. Evaluation of Scattered Light Intensity in the Forward Small Scattering Angle Region
The SALD-7100 Nanoparticle Size Analyzer was developed for the purpose of measuring particle size distribution. However, its capabilities are not limited solely to this; it can also be used as a high-resolution detector of scattered light intensity in the forward small scattering angle region. The scattered light intensities with respect to the scattering angle can be detected and evaluated at 20 points in a small scattering angle range of less than one degree...


5. Measurement of Diameter of Micro-bubbles and Nano-bubbles (Part 2)
When air bubbles in water become smaller in size and reach the micro and nano levels, they come to have a variety of unique physiochemical properties. Currently, research into application of Micro-bubbles and Nano-bubbles is being conducted on a wide industrial front, however, evaluation of their properties and research into manufacturing technology...


6. High-Sensitivity Particle Size Distribution Measurement of Liposomes
Since the SALD-7100 Nanoparticle Size Analyzer uses a UV laser as its light source, it can measure particle size distribution of low-concentration samples with higher sensitivity than analyzers using a red laser. For example, it can measure liposomes having a particle size distribution of between about 100 to 500 nm...


7. Measurement of Diameter of Micro-bubbles and Nano-bubbles (Part 3)
Effective use of Micro-bubbles/Nano-bubbles is being examined not only in tap water or ion exchange water, but also in seawater, physiological saline and further in various media and solutions. In this case, how bubble diameter or amount of generated bubbles changes according to the liquid used is a factor determining the effect of the Micro-bubbles/Nano-bubbles, and is an extremely important research theme being promoted towards its practical application...


8. Evaluation on Scattering Characteristics of Optical Films and Filters at Forward Small Angles

9. Evaluation on Scattering Characteristics of Optical Films and Filters at Forward Small Angles (Part 2)
Though optical films are used for anti-reflection, surface protection, and other purposes on LCDs, plasma (PDP) screens and organic EL displays, they sometimes cause "blurring" or "opaqueness" of images. Though these characteristics were conventionally evaluated visually, if the optical system of the SALD-7100 Nanoparticle Size Analyzer is used...


10. Measurement of Diameter of Micro-bubbles and Nano-bubbles (Part 4)
There are still many unknown issues remaining in the area of Micro-bubbles and Nano-bubbles though their practical application is highly anticipated. One of such issues that cannot be easily solved is judgment as to whether bubbles in water are actually real air bubbles or particles...


11. Measurement of Colloidal Silica (Utilization of Diffracted/Scattered Light Intensity Distribution Data)
Since the particle size of colloidal silica can be controlled, it can be used to make raw material having a relatively uniform particle size. Therefore, application of colloidal silica is now being investigated into various materials including catalysts and coating materials. This time the Shimadzu SALD-7100 Nanoparticle Size Analyzer was used to...


12. Measurement of High-Concentration Samples - Particle Size Distribution Measurement of Medicated Hand Soaps -
There exists a persistent need to measure samples in their original state without diluting them, even if they are high-concentration. However, when a regular flow cell or batch cell is used to measure high-concentration samples having a particle concentration of several hundred ppm or more, multiple scattering occurs, preventing accurate measurement...


13. Measurement of High-Concentration Samples (Part 2) - Measurement of Sports Drinks -
The SALD-7100 can measure fairly high-concentration samples without the need to dilute them if the optional SALD-HC71 is used. However, with medium concentration samples of about several hundred ppm, the optical path length will be too short if the sample is simply inserted between two glass slides, and sufficient scattered light intensity cannot be obtained...


14. Measurement of High-Concentration Samples (Part 3) - Influence of Multiple Scattering in Measurement of Milk -
The SALD-7100 can measure fairly high-concentration samples without the need to dilute them if the optional SALD-HC71 is used. In this configuration, the influence of multiple scattering should be taken into consideration the most. Generally, in circumstances where the adverse influence of multiple scattering cannot be ignored, it is said that the particle size distribution becomes smaller than the original distribution...
