Chemical Contamination Prevention System
Industrial Clean Room (ICR) Technology | Countermeasures Against Molecular Contamination Technology
What is Industrial Clean Room (ICR) technology?
Low-Cost, Low-Energy component techniques or total engineering technologies that electronics industry requires; air cleanliness, high-precision temperature, humidity and airflow environments, and countermeasures against molecular contamination or microscopic vibration.
What is molecular contamination control technology?
Comprehensive countermeasures for molecular contaminants to be removed from production environments in ICR, such as prevention of external incursion, internal generation from building or facility materials, and so as rapid removal of generated pollutants.
- Want to eliminate harmful substances/viruses
- Want to lift productivity
Based on our vast expertise, unique technologies, and proprietary databases, we provide AMC-proof cleanrooms that are fit just for your requirements.
Our design and construction technologies allow us to select equipment and materials with few chemical contaminants to meet our customers' needs, and to quickly remove chemical contamination occurred during construction work.
Our Concept of Chemical Molecular Contamination Countermeasures
High-precision analysis of airborne chemical components for cleanrooms
To achieve a highly precise trace analysis of airborne chemical components in a completed cleanroom, it is necessary to minimize chemical contaminations due to human sampling intervention. To address this challenge, we have developed a high-precision analytical system for airborne chemical components, which has been utilized to analyze airborne chemicals in a large number of cleanrooms. Our analytical system for airborne chemical components can analyze any cleanroom in the world.
Chemical Components Produced in Cleanrooms
The airborne chemical contamination sources in a cleanroom include the construction materials of the room, staff members in the room, and process gases and chemical solutions. The following table lists the chemical components stemming from sources such as cleanroom construction materials.
