Overview:
PA-9001DLS Nano Particle Size and Potential Analyzer is a new high-end dynamic light scattering particle size analyzer product launched by LabGeni which has dual testing capabilities of zeta potential and nano-particle size.
PA-9001DLS uses electrophoretic light scattering technology to measure zeta potential and obtain isoelectric point. Compared with other instruments of the same type at home and abroad, it has significant advantages, and can be used in various experiments in conjunction with the laser particle size distribution analyzer.
Application:
PA-9001DLS Nano Particle Size and Potential Analyzer has both zeta potential and nano particle size analysis and testing functions. It is suitable for particle size and surface potential measurement of a variety of different nanoemulsions, suspension colloids, etc. It can be widely used in fine chemical industry nanomaterials, R&D and production quality control of surfactants, oligomers, etc. It is also a product development and quality control testing instrument for inks, pharmaceutical preparations and other industries.
Main Features:
| Test principle | Using the principle of electrophoretic light scattering and photon correlation spectroscopy, the size of particle Zeta potential was determined according to the electrophoretic movement speed of particles in liquid. The population velocity of the electrophoretic motion of the particles, and the amount of Doppler shift of the scattered light caused by the laser irradiation of these particles, varies. Photon correlation spectroscopy analyzes the size of particle Zeta potential according to the frequency shift. |
| Ultra-high-speed data acquisition | The core component of the instrument is through the HA1024 digital correlator, which can complete the collection of electrophoretic scattered light intensity and the calculation of the auto-correlation function in real time, so as to effectively reflect the information of the electrophoretic movement speed of the particles and lay the foundation for the accuracy of the Zeta potential test results. |
| High sensitivity signal-to-noise ratio | Using professional-grade high-performance photomultiplier tubes, it has extremely high sensitivity and signal-to-noise ratio to photon signals. |
| High-precision constant temperature control | Using semiconductor temperature control technology, the temperature control accuracy is as high as 0.1 °C, so that the sample is always in a constant temperature state during the whole test process, avoiding the test deviation caused by the change of liquid viscosity and Brownian motion caused by temperature changes, and ensuring the accuracy and stability of the test results.
|
| Stable optical path system | The optical path system constructed by the optical frequency shifting device and the optical fiber coupling technology makes the detection system not only small in size, but also has strong anti-interference ability, thus ensuring the stability of the test. |
