Ensuring Long-Term Stability of Calibration Gas Concentrations in Plastic Bags

In industries where precision and reliability are paramount, maintaining a stable modified atmosphere within plastic bags over extended periods is a challenging yet crucial task. Gasporox, a leader in advanced gas measurement technologies, has developed a groundbreaking solution to this problem. By leveraging innovative techniques and materials, Gasporox provides plastic bags with long-term stable gas concentrations, ensuring accurate and dependable calibration for various applications.

The Challenge of Maintaining Stable Gas Concentrations

Plastic films, commonly used in packaging, naturally allow gas exchange with the surrounding environment. Over time, this diffusion process causes the gas concentration within the bag to equilibrate with the ambient atmosphere. This poses a significant challenge for applications requiring precise gas concentrations, such as calibration of gas measurement instruments. Factors influencing this process include the type of gas, the composition of the plastic film, temperature, and environmental conditions.

Gasporox’s Innovative Solution

Gasporox has developed a specialized procedure to maintain stable gas concentrations in transparent plastic film bags for over six months. This breakthrough allows the use of gas-filled bags for reliable on-site verifications and calibrations.

Key features of Gasporox’s solution include:

• Specialized Materials: Utilizing specific materials within the bags, Gasporox stabilizes gas concentrations effectively. This is particularly efficient for oxygen, though the stabilization of other gases may not always be feasible without these specialized materials.
• Controlled Environment: By meticulously controlling the environment during the filling and sealing process, Gasporox ensures that the initial gas concentration is precisely set and maintained.
• Long-Term Stability: The validated procedure guarantees that the gas concentration remains stable for more than six months. This is a significant advancement over traditional methods, which struggle to maintain stability over shorter periods.

Applications and Benefits

This innovation is particularly valuable for the calibration of Gasporox GPX1500 Film instruments. The ability to use gas mixtures such as oxygen or carbon dioxide in nitrogen at concentrations like 80%, 50%, or 2% ensures precise calibration and verification processes.

Benefits of Gasporox’s Solution

• Accuracy: Ensures that calibration gases have the specified concentration at the time of measurement, critical for accurate calibration.
• Reliability: Long-term stability minimizes the need for frequent replacements, reducing operational costs.
• Versatility: Applicable to various gas mixtures, enhancing the flexibility of calibration processes.

Conclusion

Gasporox’s development of long-term stable plastic bags with controlled gas concentrations marks a significant advancement in gas measurement technology. By addressing the challenges of gas diffusion and concentration stability, Gasporox provides a reliable and efficient solution for industries requiring precise gas calibration. This innovation not only enhances the accuracy and reliability of gas measurement instruments but also offers cost-effective benefits, reinforcing Gasporox’s position as a leader in the field.
