Ensuring Cleanliness and Product Quality
In industries such as aerospace, automotive, semiconductors, and medical devices, maintaining the highest level of cleanliness is critical. Even a microscopic particle can affect performance, reduce product lifespan, or — in the case of medical implants — pose serious health risks.
To meet strict cleanliness standards, manufacturers apply advanced cleaning processes, many of which now use water-based solutions to comply with environmental regulations. However, no matter how thorough the cleaning process is, verification is essential. This is where Liquid Particle Counters (LPCs) come into play.
Why LPCs Matter
LPCs are core instruments for real-time contamination monitoring in cleaning fluids. They deliver immediate feedback, helping manufacturers validate the cleaning efficiency of every process cycle.
Advanced models, such as the Lighthouse Vertex50, offer 50 nm sensitivity and support continuous, high-accuracy monitoring — enabling optimal contamination control throughout production.
Industrial Cleaning Methods and the Role of LPCs
1. Ultrasonic Cleaning
High-frequency sound waves generate millions of microscopic bubbles that dislodge contaminants from complex surfaces.
Industries: Semiconductors, Aerospace, Medical Devices, Automotive, Data Storage
LPC Role: Measures particle concentration in the cleaning solution to verify final cleanliness.
2. Immersion Cleaning
Parts are immersed in a solvent or water-based solution, often combined with ultrasonic cleaning for improved efficiency.
Industries: Semiconductors, Aerospace, Medical Devices, Automotive
LPC Role: Compares particle levels before and after cleaning to assess process effectiveness.
3. CO₂ Cleaning
Uses solid or liquid carbon dioxide to remove contaminants without leaving residues.
Industries: Semiconductors, Medical Devices, Aerospace, Data Storage
LPC Role: Confirms there are no residual particles remaining after cleaning.
4. Passivation
Removes ferrous particles from stainless steel to enhance corrosion resistance according to ASTM A380 and A967.
Industries: Aerospace, Medical Devices
LPC Role: Verifies complete particle removal and ensures surfaces meet cleanliness standards.
