Selecting the Right Tool for Testing Material Permeability-1

Labthink Instruments Co., Ltd. [email protected] +86-531-85068566 Permeability Permeability refers to a material's ability to allow a substance, such as a gas or vapor, to pass through it. It is an inherent property of the material and plays a crucial role in packaging applications. Materials with low permeability are ideal for preserving the shelf life of products by restricting oxygen and moisture ingress. Two primary methods are employed for permeability testing, differential pressure method and sensor method. Differential pressure method is widely used and involves creating a pressure difference across the test material. One side of the sample is exposed to the target gas or vapor at a higher concentration, while the other side is maintained at a lower concentration. Instruments employing this method typically measure the flow rate of the permeating substance across the material under a constant pressure difference. Labthink C101B, C106H , C130H and VAC-V2 Gas Permeability Testers are developed based on the differential pressure method. These instruments measure the permeability of various gases like oxygen, carbon dioxide, and nitrogen. They are often automated and can analyze several samples simultaneously.

Labthink Instruments Co., Ltd. [email protected] +86-531-85068566 Sensor method utilizes sensors to detect the permeating gas or vapor directly. These sensors can be electrochemical or optical, depending on the specific gas being measured. While less common than the differential pressure method, sensor-based instruments offer advantages like faster testing times and higher sensitivity for certain gases. Several factors influence the selection of a suitable test method and instrument, such as type of permeate, testing standards, material properties and testing conditions. In addition, temperature,...
