By monitoring dissolved oxygen, we solve issues related to oxidation and foaming.

Are you having trouble with "foaming" and "oxidation" in your research and development or manufacturing processes? The cause may be related to "dissolved oxygen (DO)."

During the transportation and storage of substances that are prone to foaming or oxidation, chemical changes can occur that affect quality, so it is necessary to frequently measure the amount of oxygen. Orbisphere is a series of high-precision dissolved gas analysis instruments suitable for both liquid and gas phases. In addition to measuring dissolved oxygen (DO) in chemical and organic solvent applications, we offer a variety of installation methods tailored to different uses, including inline, online, and laboratory measurements, as well as portable models, explosion-proof models certified by IECEx and ATEX, and parts resistant to chemicals suited for the measurement samples, providing a rich lineup. Currently, we are introducing examples and topics related to oxygen measurement using Orbisphere. [Overview of Downloadable Materials] ■ Dissolved oxygen measured in many industrial fields ■ Examples of oxygen measurement applications in petrochemicals ■ Oxygen measurement in breweries ■ What is dissolved oxygen (DO: Dissolved Oxygen)? ■ List of application-specific products ■ Installation image of dissolved oxygen meters *For more details, please refer to the PDF materials or feel free to contact us.

[Application Example] Improving Factory Yield and Regulatory Compliance

Achieved through online TOC! Introducing a case study that improved factory yield and reduced product loss.

We would like to introduce a case study of the implementation of the "BioTector B7000" at a dairy processing company. The product loss in the company's wastewater not only reduced the factory's yield but also caused significant variability in the wastewater treatment process, leading to risks of environmental compliance violations and increased operational costs. After implementation, identifying the source of product loss reduced the variability in the load on the treatment plant, making compliance easier to achieve. 【Case Summary】 ■ Benefits of Implementation - Meets regulatory requirements regardless of the inflow of organic matter - Measures and optimizes the dosage of chemicals for organic matter in real-time - Improves factory yield and reduces product loss *For more detailed information about the case, please refer to the related link. For further inquiries, please feel free to contact us.

[Topic] Daily Management of FDA Process Validation Stage 3

Utilizing TOC measurement! Introducing the effectiveness of QbD1200+ in cleaning validation and more.

Stage 3 of the FDA's process validation guidance, which focuses on managing manufacturing processes and quality assurance, requires verification that the marketed products exhibit consistent product quality as designed in Stage 1 and Stage 2. For this verification, the setting, management, appropriate monitoring of process parameters, and the use of data analysis and statistical methods are essential, and the results provide important data for improving process reliability and quality. In particular, there is currently active discussion regarding Stage 3 of cleaning validation, which is one of the critical initiatives in pharmaceutical manufacturing. *For more details, please refer to the related link.

[Overseas Case] Maintaining Compliance for Phosphate Emissions

Accelerating the exploration and tracking of pollutants! Introducing examples of compliance with phosphate discharge regulations.

We would like to introduce a case study of the introduction of the "BioTector B7000" at the wastewater treatment plant in Oijen, Netherlands. This wastewater treatment plant did not have a component analysis device to monitor inflow and outflow water, and relied on regular inspections by a third-party organization. As a result, they were unable to respond swiftly to the sudden increase in C/N/P loads from industrial wastewater. After the introduction, it became possible to reliably monitor C/N/P levels during wastewater treatment. 【Case Overview】 ■ Challenges - Unable to respond swiftly to the sudden increase in C/N/P loads from industrial wastewater. ■ Results - It became possible to reliably monitor C/N/P levels during wastewater treatment. *Details of the case can be viewed through the related link. For more information, please feel free to contact us.
