Test Principle
The pre-conditioned specimen is mounted between the upper and lower chambers at ambient atmospheric pressure. The upper chamber contains oxygen or air and the lower chamber is slowly purged by a stream of nitrogen. Due to the concentration difference between the two chambers, oxygen molecules permeate through the specimen into the nitrogen side and are taken to the coulometric sensor where proportional electrical signals are generated. The oxygen transmission rate is then obtained by analyzing the signals and calculating the volume of oxygen measured by the sensor. For whole package samples, high purity nitrogen flows inside the package, and oxygen or air flows outside.

FAQ's of Oxygen Transmission Rate (OTR) Testing for Protein Powder Bags:
Q: How does the Oxygen Transmission Rate Tester measure oxygen permeability in protein powder bags?
A: The OTR Tester measures the rate at which oxygen passes through packaging materials using a coulometric or manometric technique as per ASTM D3985/ISO 15105-2. The specimen is clamped between chambers, where oxygen permeability is determined by monitoring changes in the test gas, providing accurate barrier property data.
Q: What is the recommended process for calibrating the tester?
A: Calibration can be performed automatically or manually using the built-in calibration feature. Regular calibration is recommended to maintain accuracy, especially before starting a new series of tests or after any significant equipment maintenance.
Q: When should OTR testing be conducted on protein powder bags?
A: OTR testing should be performed during packaging development, quality control, and material validation stages. This ensures that the bags meet necessary oxygen barrier requirements to preserve protein powder quality throughout its shelf life.
Q: Where can this OTR tester be used, and what are the environmental requirements?
A: This tester is suitable for laboratory environments in packaging manufacturing and quality control sectors. It should be used in a dust-free and vibration-free area, with ambient temperatures between 10-35C and controlled humidity between 10%-90% RH for optimal performance.
Q: What makes this OTR tester beneficial for packaging analysis?
A: It features high measurement accuracy (2%), quick response time (30 seconds), and supports up to 1000 record storage. Its automatic operation, high sensitivity, and digital LED display contribute to improved efficiency, reliable results, and comprehensive data management.
Q: How is sample testing conducted using this equipment?
A: A sample (up to 100 mm x 100 mm, up to 3 mm thick) is placed in a leak-proof clamp fixture. Testing parameters such as speed and temperature are set via microprocessor control, and the test is run automatically. The software records and displays results for future analysis.
Q: What types of packaging can be tested with this instrument, and what is the test range?
A: Besides protein powder bags, any packaging films or materials within the thickness (up to 3 mm) and size (100 mm x 100 mm) limits can be tested. The measuring range is from 0.1 to 2000 cc/m224h, suitable for a broad spectrum of materials with different barrier properties.
