Quality and Reliability

Our Effort in Safety

A wide variety of solvents are being used in the Japanese industry, and waste solvent is being discharged. Waste solvents contain impurities other than the solvents, and there is a great potential danger.

In our company, we are using various analytical equipments such as the new analytical instrument ARC, and are putting a strict checking procedure to ensure safety from the process development of the distillation refining up to the shipment of the recycled product.

In addition, we are putting our efforts to further ensure safety by changing the specifications of the equipment to improve safety, ensure safety education to the frontline workers, etc.

Our Effort in Quality

Quality control of metal content in ppt units for high-purity solvents

In the clean room inside the Chiba plant, we are measuring the metal content in high-purity solvents in ppt (parts per trillion) units.

 

To obtain stable results (numbers),
  • It is important to take care to maintain a stable environment. Especially, the air conditioning and particle management in the clean room is critical. In order to minimize external influence, we are controlling the sections using air showers, and the clean room is at Class 10,000 (an environment that guarantees that particles larger than 0.5 microns is under 10,000 per square feet ( ≈ 28.3 L)), and the analytical equipment is placed inside a clean booth controlled at Class 100.
  • Measurement in ppt units is conducted by an analyst who is experienced in the measurement techniques, and verifications to maintain the measurement techniques are conducted periodically.
