Description
| 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 samples of less than 1ppm can be measured. |
| Enables measurement of fine bubbles (micro bubbles from 100 nm to 60 μm), |
| and allows real-time tracing of the changes in the bubble diameter. |
| This system enables the evaluation of sub-visible particles included in biopharmaceuticals. |
| Special options can be added to create an aggregation property evaluation system for biopharmaceuticals. |
| Wide Measurement Range : 7 nm to 800 μm |
| From primary particles to sub-visible particles and contaminants |
| Changes in particle size across the 7 nm to 800 μm 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. |
| The evaluation of the dispersion and aggregation characteristics of the particles is realized with a |
| wide measurement range and in real time. |
| 1-Second Minimum Serial Measurement Time. Real time monitoring |
| By incorporating a single light source, which does not require switching, and the wide-angle detection method |
| , the measurement time can be reduced to a minimum of 1 second. In addition, the particle size distribution |
| can be displayed in real time at 1-second intervals. |
| Serial observations of the dispersion, cohesion or dissolution reaction processes are possible at |
| 1-secondintervals, and these results can be saved. Functions for statistical processing and 3D display of |
| the particle reaction processes offer multifaceted analyses and evaluations. |
| Connecting the flow cell directly to the fine bubble generator enables in-line real-time monitoring of the |
| changes in fine bubbles. |
| Measure Concentrations from 0.1 ppm to 20% |
| Compared to other instruments, the SALD-7500nano permits measurements across an extremely broad |
| concentration range of 0.1 ppm to 20%. |
| The particle size of fine particles, particularly nano particles, varies with the concentration. |
| The dispersion and coagulation of nano particles can be observed while altering the concentration. |
| Accurate analysis of samples in which the particle size distribution changes with dilution is possible, |
| as measurements can be conducted on the undiluted solution or after minimal dilution. |
| For example, commercial hand creams, face creams, and rinses can be measured with hardly any pretreatment. |
| Measurement of Small Sample Amounts |
| Drainage of a small quantity of a suspension liquid is adequate since the SALD-BC75 batch cell permits |
| analysis of a volume of just 5 cm3. Most organic solvents can be used. |
| A combination of the SALD-HC75 high-concentration sample measurement system with special glass |
| slides featuring a shallow indentation permits measurement on just 15 micro liters. |
