Title:
容器および密閉部材のガス透過度測定方法
Document Type and Number:
Japanese Patent JP2010503848
Kind Code:
A
Abstract:
A device that carries out a method for measuring permeability to a gas sample through a container (2) comprises an inlet duct for the gaseous carrier, in particular, nitrogen, both as inlet in the container (2) and as inlet in the chamber (1) and out of the container (2) of which permeability has to be measured. The inlet duct that exits in the container (2) comprises two ducts (11 and 8), whereas the inlet duct that exits out of the container (2) comprises two ducts (6 and 7). Such inlet ducts have an origin in common in order to allow the distribution between them of the flow (200) of gas carrier as input. An inlet duct is provided (10) for a test gas flow, such as oxygen, which ends in the duct (7) to be measured, with the gas carrier in the chamber (1). A gas-mass regulator is provided for each inlet duct (5, 4 and 3).
