  • Page 28: Water Traps

    Technical description 4.1.4.3 Water traps The analyzer multi N/C 2100 contains water traps to protect the detector and the gasbox. Two water traps are installed between the TIC condensation vessel and the halogen trap. They prevent condensed water from entering the measuring gas line. The larger water trap (TC pre-filter) retains aerosol during operation, the smaller water trap (disposable retention filter) retains rising water.

  • Page 29: Detectors

    Technical description 4.1.5 Detectors 4.1.5.1 NDIR detector The NDIR detector (NonDispersive Infrared absorption Detector) is behind the right-hand side wall of the analyzer. Gases with molecules from different atoms have specific absorption bands in the infrared wavelength range. When a light beam is sent through an arrangement of cells which con- tains gases in the IR active range, these gas components absorb a proportional part of the total radiation according to their concentration part in the gas mixture on their characteristic wavelengths.

    Transport and storage Transport and storage 10.1 Transport 10.1.1 Preparing the analyzer for transport WARNING! RISK OF BURNS AT THE HOT FURNACE! There is a risk of burns at the combustion furnace! Only remove the combustion furnace when the device is cold or allow the device to cool down sufficiently! CAUTION! RISK OF INJURY FROM GLASS BREAKAGE! When removing the glass components there is a risk of injury from glass breakage! Re- move all glass components carefully from the analyzer!

    Transport and storage 14. Attach the top cover and secure it with adhesive tape. 15. Carefully package the accessories, in particular protect glass components against breakage. 10.1.2 Transport notes Observe the safety instructions in section "Safety instructions, transport and installation" p. 9. Transport the analyzer very carefully to prevent damage from impact or vibration.

    Transport and storage 10.2 Storage CAUTION Environmental influences and condensate formation can destroy individual components of the analyzer! The analyzer must only be stored in acclimatized rooms. The atmosphere must be low in dust and free from aggressive vapors. If the analyzer and add-on devices are not positioned immediately after delivery or are not required for a prolonged period of time, they should best be stored in their original packag- ing.

    Transport and storage 10. Install the TIC condensate vessel (see section Cleaning the TC condensate vessel" p. 71). 11. Install the halogen trap and the water traps (see sections "Replacing the water traps" p. 63 and "Replacing the halogen trap" p. 65). 12.
  • Page 101 Transport and storage Connect the mains cable CAUTION Always electrically connect the system components to the multi N/C 2100 when it is switched off! Before connecting the mains cable, ensure that the main switch on the back of the equip- ment is set to "0"! Only use the IEC connection cable included in the scope of delivery for the connection to the mains supply (VDE label, 1.5 m long).

    Disposal Disposal 11.1 Waste water ENVIRONMENTAL PROTECTION The neutralized waste must be brought to the appropriate waste disposal center for correct disposal according to the appropriate legal guidelines. Waste water arises during the ongoing analysis operation of the multi N/C 2100. This water contains hydrochloric acid, diluted phosphoric acid and sample, depending on the measure- ment mode.
