EMIA-Step

Carbon/Sulfur Analyzer

In addition to the “EMIA-Expert/Pro” series of high-frequency induction furnace type, the “EMIA-Step” of tubular electric resistance heating furnace type has been newly added to our Carbon/Sulfur Analyzers lineup. It realizes highly accurate and sensitive analysis, and its variable heating temperature function enables the quantitative analysis by separating it by temperature and condition as well as whole quantity analysis.

Segment: Scientific
Manufacturing Company: HORIBA, Ltd.
  1. Enables temperature control starting at a low temperature range

    EMIA-Step provides good temperature stability from low to high temperatures. This broadens the application range to samples containing substances that are easily decomposed and burned at low temperatures.

    <Temperature rise control from 300 °C to 900 °C>
    You can easily see the decomposition combustion of organic matter and inorganic matter respectively.
     
  2. New dust-filter provides easy maintenance capability

    EMIA-Step adopted the proven dust-filter mechanism in the high frequency induction heating models. The filter unit collects the dust generated by combustion at high temperature. This prevents the dust from adhering to piping after the combustion furnace, and reduces adsorption of CO2 and SO2 gases by dust. This mechanism makes highly accurate and sensitive analyses possible.

  3. User-friendly software navigation functions facilitate the operation

    <Analysis Navigation>

    Recommends the best measurement flow and analysis conditions based on our experience. 


    <Troubleshooting Navigation>
    Pinpoints the location automatically, and notifies the operator with the recovery procedure when any fault occurs.  


    <Maintenance Navigation>
    Daily maintenance menus are listed and the videos and photos of the maintenance procedures are displayed.
