The power switch is located on the front panel in the low left hand corner. Set to position 1. The reason why to first switch on the analyzer is for the infrared detectors to have time to stabilize their temperature while cable connections and software start are made.

  • Page 19: Gas Connections

    Installation cables are included in the boxes of additional peripheral devices supplied with the analyzer. These are adapted to the interfaces when the analyzers are put into operation in our company. The serial interface of the balance is programmed in order to match the required configuration for weight transfer to the PC.

  • Page 22: Autoloader (Optional)

    The CS-2000 can be supplied with an automatic sample loading system. This loading system may also be retrofitted at a later date. Unlike many other auto loaders, the ELTRA system can accommodate 130 samples giving hours of unattended operation. On request, the loader can be delivered for more crucibles.

  • Page 23: Analysis

    For eye protection use the supplied protective glass. With the CS-2000 a wide variety of materials can be analyzed. The analysis methods are therefore diverse. As different materials burn differently, the chosen sample weight, the possible accelerators, the procedure for the insertion of the sample into the furnace and, finally, the sensitivity of the infrared cell will be different.

When analyzing samples with low concentration of carbon or sulfur (<1000 ppm), the pre- heating of the crucibles is advisable. The crucibles contain traces of carbon, which can vary from 20 to several hundred ppm, depending on their quality.

  • Page 30: Tic-Determination (Optional)

    5.5.1 TIC-module Due to the modular design of the CS-2000, a module for Total Inorganic Carbon (TIC) can be placed between the resistance furnace and the analyzer. For the TIC determination, the sample is treated with acid in the TIC module.

Good results can be obtained by using quartz boats. There is no chance to measure in this low range if you use ceramic boats. Their blanks and their deviations are huge compared to the sample’s carbon.
  • Page 41 Analysis For even lower carbon samples, a furnace extension piece, supplied by ELTRA, needs to be attached to the furnace inlet. The reason is that the thick short combustion tube allows some air to enter the combustion area. The air contains CO2 which is detected by the carbon cell. As the CO2 concentration resp.

  • Page 78: Function Description

    The CS-2000 can be supplied with up to three independent Infrared cells, giving the following options: Two IR-cells for carbon and one for sulfur.

  • Page 79: Gas Flow System

    Function description 7.3 Gas flow system The oxygen supply is connected to the inlet of the gas flow system. Pure oxygen is available in steel bottles. A 99.5% purity is fully sufficient. Any CO2 or H2O which may be contained in the oxygen is retained in the CO2 and H2O trap.
  • Page 80 Function description Fig. 51: Gas flow system...

  • Page 81: Infrared Cell

    The signal obtained is amplified and rectified, so that the infrared cell output is DC voltage. The detectors utilize solid state sensors combined with infrared filters. The sensors are not gas filled, thus eliminating long term problems due to gas leakage. The CS-2000 can be equipped with up to four independent Infrared cells.

  • Page 82: Furnace

    The users of carbon and sulfur analyzers with induction furnaces know that dust accumulates during the combustion (mainly of iron and tungsten oxides) in the combustion chamber. The CS-2000 induction furnace is cleaned automatically after each analysis, thus ensuring repeatable and accurate results. The cleaning mechanism is mechanically attached to the furnace open/close system, to ensure that the cleaning brush will not collide with the hot crucible.The cleaning brush will never burn.

  • Page 83: Resistance Furnace

    Function description 7.5.2 Resistance furnace Description The temperature of the furnace is adjustable up to 1550°C. The combustion tube has an inner diameter of 27 cm and a hot zone of about 200 mm. The temperature, which is digitally displayed, can be adjusted with an accuracy right down to 1°C. The platform on the front-side of the furnace serves to carry samples for the analyses, as well as hot combustion boats, after been removed from the furnace.
  • Page 84 Function description This is important for analysis in the very low ppm range. The crucibles are inserted into the furnace tube and they remain preheated in the tube until needed. Each time a crucible is needed, a new one is inserted into the tube, and a preheated crucible falls out the other end of the furnace tube.
