Specifications
System Features
All systems consist of a sensor, pulse height analyzer (counter), and fluidics to transport the sample through the sensor. Particles flowing through the sensor scatter and obscure the incident laser beam. This light interaction creates pulses that are proportional to the particle size. The counter converts these pulses to particle size.
| Sensors: | LE400 | Collimated beam, scatter + extinction, 0.5-400 μm |
| FX | Focused beam, extinction 0.7-20 μm at high concentration | |
| FX-Nano | Focused beam, scatter 0.15-10+ μm at high concentration | |
| LE1000 | Extinction, 2-1000 μm | |
| LE2500 | Extinction, 25-2500 μm | |
| Counter: | The counter provides high resolution results in up to 1024 size channels | |
| Fluidics: | The sample can be transported through the sensor either without dilution or with single and two stage autodilution samplers | |
High Resolution Particle Counters
AccuSizer SIS System
