Particle Size & Zeta Potential Analyzer
Liquid Particle Counter Accusizer A7000
The AccuSizer product line is based on our unique single particle optical sizing (SPOS) technology. The SPOS systems can be used as liquid particle counters for contamination applications or as sophisticated particle size analyzers of suspensions.
All AccuSizer 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 proportion to the size of the particle. The counter converts these pulses to particle size.
Sensors
- The LE400 sensor; collimated beam, scatter + extinction, 0.5-400 µm
- The LE1000 sensor; extinction only, 2-1000µm
- The LE2500 sensor; extinction only, 25-2500µm
Counter
- The counter provides high resolution results in up to 512 size channels
Systems
- A7000 SIS: USP 787, 788, or 789 testing of parenteral drugs or ophthalmic solutions
- A7000AD: Single stage auto-dilution for general particle size analysis applications
- A7000APS: Two stage auto-dilution for high concentration samples and USP 729 testing
