Principle

The pre-conditioned specimen is mounted in the gas diffusion cell as to form a sealed barrier between two chambers. The lower-pressure chamber is firstly evacuated, followed by the evacuation of the entire cell. A flow of gas is thereafter introduced into the evacuated higher-pressure chamber and a constant pressure difference is generated between two chambers. The gas permeates through the specimen from the higher pressure side into the lower side. The gas permeability and other barrier properties of the specimen can be obtained by monitoring the pressure changes in the lower chamber

FAQ's of Testing Film Diffusion Coefficient for Packaging Performance:

Q: How does the differential pressure method work in testing film diffusion coefficient?

A: The equipment uses the differential pressure method, which measures the rate at which a gas permeates a film by tracking pressure changes across the specimen. This principle ensures accurate assessment of a material's barrier properties for packaging applications.

Q: What types of materials can be tested with this instrument?

A: The device is compatible with a broad range of films, including plastic, metal, and composite materials. This versatility makes it suitable for evaluating various types of packaging and barrier materials used in the industry.

Q: When should I perform calibration on the tester?

A: Calibration is managed with a built-in standard system, ensuring long-term measurement reliability. It is recommended to verify calibration before starting a new batch of tests or if measurement accuracy is in question.

Q: Where can the test results be stored and exported?

A: Test results are stored within the device's memory, with a capacity of up to 1000 records. Data can be exported via RS232 or USB interfaces, facilitating easy integration with laboratory information systems or external data analysis tools.

Q: What is the process for loading and testing samples?

A: Samples measuring 100 mm x 100 mm are manually clamped into the test chamber (up to three specimens at once). The microprocessor-controlled system automates the diffusion testing, with direct digital display of results and real-time data monitoring.

Q: How does the equipment ensure safety during testing?

A: The tester features overload protection and an emergency stop function, providing immediate intervention in the event of abnormal operating conditions. It is built according to RoHS and CE standards, ensuring both operational safety and environmental compliance.

Q: What benefits does real-time monitoring and automatic data acquisition provide?

A: Real-time monitoring and automatic data acquisition minimize human error, allowing continuous supervision of testing conditions and immediate access to results. This streamlines the workflow and enhances result accuracy and reliability.
