Product Details
A monodisperse aerosol generator is a scientific instrument used to generate uniformly sized and highly stable aerosol particles, widely used in environmental monitoring, air purification, medical device testing, scientific research experiments, and other fields.
1. Core principles
Monodispersity: aerosol particles with extremely narrow particle size distribution (usually RSD<10%) are generated by physical or chemical methods (such as vibrating holes, electric spray, condensation, etc.).
Key technologies: such as vibration hole technology, which uses piezoelectric ceramics to drive micro porous plates to generate uniform droplets, and then evaporates the solvent to obtain solid particles; The electric spray law uses a high voltage electric field to make the liquid form a Taylor cone and break into monodisperse droplets.
2. Core parameters
| Key Metrics | parameter range |
| principle | Ultra high speed oscillation occurs |
| particulate matter | reference material |
| particle size range | 0.05μm~50μm |
| Particle concentration | (0~40000) pieces/L (10 μ m particles) |
| Adjust the flow range | 5~50L/min， Optional 10~150L/min |
| Channel occurrence | Multi channel optional |
3. Typical application scenarios
Medical device testing: testing the filtration efficiency of masks/filter materials.
Laboratory research: aerosol dynamics, cloud physics simulation, virus transmission models, etc.
Industrial field: semiconductor cleanroom validation, spray coating process optimization.
Calibration purpose: As a standard particle source for calibrating optical particle counters or time-of-flight mass spectrometers.
4. Technical advantages
High precision: Compared to multi dispersion generators, it can provide more controllable experimental conditions.
Repeatability: The particle size consistency of multiple experiments under the same parameter is greater than 95%.
Modular design: Some models support the replacement of porous plates to meet different particle size requirements.
