Abstract: A fluid filtering device for separating liquid from gases to be analyzed, including a tubular housing defining a space therein and having inlet and outlet end portions delimiting passageways in fluid communication with the space, the portions being connectable between a source of fluid and a gas analyzer, and a liquid/gas hydrophobic hollow fiber filter element located within the tubular housing preventing material other than gases to pass therethrough. The tubular housing and filter element form a small volume within the housing, and the device is effectively operable independent of its orientation, or field of gravitation acting thereon.
