Most commonly, replenishers are used with hydrogen ; a filament made from a hydrogen-absorbing metal ( e. g. zirconium or titanium ) is present in the tube, and by controlling its temperature the ratio of absorbed and desorbed hydrogen is adjusted, resulting in controlling of the hydrogen pressure in the tube.
