Application Field：Packaging/Food/Medicine/New material/Chemical/Printing
Function and Application
It is suitable for the oxygen permeability performance testing of films, sheets, papers, packaging components and related materials in fields such as food, pharmaceuticals, medical devices, daily chemicals, photovoltaic electronics, etc. It provides a wide range and high-efficiency oxygen transmittance detection for materials with high, medium and low oxygen barrier properties.
Test Principle
The principle of the coulometric method is adopted. The pre-treated sample is fixed in the middle of the test chamber. High-purity oxygen flows in the upper chamber of the film, and high-purity nitrogen (carrier gas) flows in the lower chamber. Oxygen molecules diffuse through the film into the nitrogen on the other side and are carried by the flowing nitrogen to the sensor. By analyzing the oxygen concentration measured by the sensor, the oxygen transmission rate can be calculated.
Product Features
1.High-precision imported oxygen sensor, with high sensitivity, ultra-high stability and extremely low failure rate, and a resolution of 0.0001cm³/(㎡·24h).
2.Accurate and reliable test data: The test temperature is precisely controlled. Equipped with a high-precision temperature sensor, the temperature and humidity in the test chamber are stable, and the temperature control accuracy can reach ±0.5 ℃.The temperature, gas flow values and curves are monitored in real time during the test, and the test has high repeatability.
3.Ultra-wide test range and high instrument applicability: The instrument is equipped with a single chamber, which is compact and flexible, saving space; with an ultra-wide test range of [0.005~1000 cm³/(㎡·24h)], it can meet the test requirements of high, medium and low barrier materials. With the addition of suitable accessories, it can measure the oxygen transmission rate of containers such as bottles, bags and bowls.
4.Intelligent operating system with global certification: Self-developed intelligent operating system with modular diagrams, flexible setting of test process parameters, and intuitive and convenient operation; Designed according to the GMP appendix "Computerized Systems", it has an audit trail function and multi-level user authority settings, which can meet the data traceability requirements of the pharmaceutical industry; Personalized test reports can be set as required, supporting various data output formats, and the function of submitting audit reports online.
