LPC (Liquid Partical Counter)
Liquid Particles Counting (LPC)
LPC (Liquid Particles Counting) is a common method to display the particulate cleanness of material surface, and is also an effective tool to measure particle size and distribution of powder material. LPC technique utilizes laser to measure particle size distribution and count particle quantity by scattering and extinction mode. When a beam of laser shines the particles in liquid, the existence of solid particles will cause light scattering with different direction and intensity, and meanwhile the photodiode will detect the change of light energy, and then transform it into electricity signal (voltage pulse), which reflects the size and quantity of the particles.
LPC Technical Capabilities
- Signal Detected: Solid particles in liquid
- Particle size range: 0.2~350µm
- Error range: ±10%
Applications for LPC Analysis
- Particle measurement of liquid (drinking water, injection, DI water etc.)
- Particle measurement of material surface/electronic components (computer hard drives, circuit board)
- Particle size and distribution measurement of powder material
- Particle measurement of consumable materials (wipers, tray, package, vessel etc.)
- Particle measurement of chemical solvent.
Relevant Industries for LPC Analysis
- Electronics (
- Nano-material
- Water disposal
- Environment/Environment protection
- Pharmacy/ iatrology
Strengths
- Convenient and fast
Limitations
- Too many factors will affect the result (like sample collect, environment etc.)
- Relatively large error range
- Can only measure particles with size above 0.2µm
