AI Overview
This video explains the process of measuring the oxygen transmission rate:
Key Features and Functions
- Methodology: Uses a "coulometric sensor method" (equal pressure method), where oxygen permeates through a sample into a nitrogen carrier stream, which then flows to a sensor that detects and measures the oxygen.
- Applications: Measures permeability in packaging films, plastic sheets, bottles, and finished containers.
- Test Conditions: High-end models allow precise control of temperature, humidity, and flow rate for accurate results.
- Standards: Conforms to international standards, including ASTM D3985 and ISO 15105-2.
- Industry Use: Widely used in food, pharmaceutical, and medical device packaging to prevent oxidation.

How is otr calculated?
OTR can be calculated by measuring the recovery of the dissolved oxygen (DO) in the bioreactor after sodium sulfite depletion. To demonstrate the process, we used a BioFlo 320 3 L glass bioreactor as an example to calculate its OTR.

How to measure oxygen transmission rate?
At a selected temperature and humidity, a barrier film is sealed between a chamber containing oxygen and a chamber void of oxygen. A coulometric sensor measures the oxygen that is transmitted through the material.
