TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: In the device: the unlocked fluid connection devices lock the fluid line connectors; and/or the fluid connection devices are designed in such a way that the fluid line connectors are locked during the unlocking of the fluid connection devices; and/or the fluid connection devices are designed in such a way that they are lockable manually or automatically using the respective fluid line connectors; and/or at least one of the fluid connection devices is designed in such a way that it is connectable and unlockable successively or simultaneously with the respective fluid line connector. The fluid connection devices respectively exhibit a fluid flow channel (19) and a movable closing element, where the closing element closes the fluid flow channel in a fluid-tight manner and the fluid connection devices are designed in such a way that the respective closing element moves by connecting the fluid connection device with the fluid line connector and opens the fluid flow channel, and/or moves by dismantling the fluid line connectors and closes the fluid flow channel. The device further comprises two fluid line connectors, which are designed in such a way that they are respectively connectable with one of the two fluid connection devices and a fluid line. In the device: the container comprises at least one adsorbent material; and/or the container comprises at least one adsorbent material for desulfurization of liquefied gas, gas or natural gas; and/or the container comprises several adsorbent materials and the adsorbent materials are present in a mixed bed or as multi component adsorbent material. The device further comprises a thermally activated fluid shut-off device and/or a fluid flow controller. The container comprises an opening- and closing element for reversible filling of the adsorbent material, which exhibits a safety device for preventing the manipulation by unauthorized persons, comprising: a cover of the opening- and closing element and a special screw connection, which can be opened only with a special tool. In the device: the container is designed in such a way that it is vertically installable and is adjacent to the fluid inlet, which exhibits a cavity or a cavity with a filling or bound of porous and/or flexible inert material or plastic foam for collecting the condensate; and/or the cartridge (10) and/or the used adsorbent material is designed in such a way that it is usable at a temperature of -10 to 90 degrees C and at a pressure of -500 bars above atmospheric pressure to 10 bars above atmospheric pressure. In the device: the container exhibits a packing length to packing diameter ratio of 0.1-40; and/or a space velocity of less than 10000 per hour is adjusted in the container, based on the total amount of the adsorbent material; and/or the packing to particle diameter ratio of the adsorbent material is greater than 10.
