Introduction
The success of the AccuSizer range of sensors in the laboratory has been extended to On-Line operations to detect particle outliers in processes such as homogenization, grinding and filtration.
A typical application for these systems is the monitoring of a critical In-line filter such as CMP (chemical mechanical polishing) slurry production.
The multiplex sampling hydraulics allow:
- Sampling from an unfiltered, upstream line with suitable autodilution.
- Sampling from the filtered product stream with the appropriate autodilution to achieve optimum counts through the detection system.
Features
- Fully automated to update a control panel of process distributions
- Eliminates the cost of premature filter replacement
- High resolution and sensitivity of particle counts
- Automated batch sample analysis
- Multiple sample trays available:
– 3×7 samples – 30 mm tube (50 mL)
– 4×10 samples – 20 mm tube (20 mL)
– 5×12 samples – 16 mm tube (14 mL)
– 6×15 samples – 13 mm tube (7 mL)
- Not all rack configurations are not available for all modules.
- Dual Trays of the sample configuration are also available.
- Modular easy lock and load sample trays
- Wide Dynamic Range Sensors:
– 0.5 nm – 400 microns (SPOS)
– 0.3 nm – 3 microns (DLS)
- Ability to pre-dilute samples such as:
– Emulsions (Food/Drug)
– Dispersions
– Proteins/Macromolecules
– Inks/Pigments/Paints
– Minerals/Alumina/Metals
– Silica packing materials (HPLC columns)
– Pharmaceutical Powders/Suspensions
Measures
- Particle concentration
- Particle counts and distribution
