Abstract
A device includes an analyzer () and a sampling apparatus () for taking a sample of at least one fraction of the gas that has at least one porous membrane element (). The porous membrane element () has a support () and a first surface () which is in contact with liquid circulating in duct () and a second surface () which opens out into a duct () which is connected to the analyzer (). The hardness of the first surface () is more than 1400 Vickers (kgf/mm), ranging more particularly between 1400 and 1900 Vickers (kgf/mm). The device can be used to analyze the gaseous content of oil well boring sludge.
