Carbon/Sulfur Analyzer (Entry Model)

Your high-precision solution for diverse samples and increased productivity

The EMIA-Pro Carbon/Sulfur Analyzer provides exceptional accuracy, streamlined maintenance and user-friendly software enhancements that enable efficient measurements. Its reduced cycle time also helps to accelerate development and manufacturing speed.

Typical Applications:
– Energy: Materials for lithium-ion battery, fuel cell, electrolyzer
– Electric parts
– Ceramics
– Semiconductor: Silicon, poly-silicon, GaN
– Steel and non-ferrous alloy (metallurgy): Iron, copper, nickel, aluminum, zinc, tungsten carbide
– Mineral: Cokes, lime stone, coal, silicone, rare-metal
– Others: Catalyst, rubber, carbon black, silica, cement

* For even higher measurement accuracy and lower detection limit, we also offer the EMIA-Expert Carbon/Sulfur Analyzer (Flagship High-Accuracy Model).

Manufacturing Company: HORIBA, Ltd.

Greater Accuracy

Proven NDIR Gas Detection Technology

The EMIA-Pro Carbon/Sulfur Analyzer utilizes the infrared method to measure the carbon and sulfur content of a sample after combustion in an induction furnace. It leverages HORIBA’s reliable Non-Dispersive Infrared (NDIR) measurement technology, providing a measurement range optimized for carbon from 1.6 ppm to 6.0% and for sulfur from 2 ppm to 1.0%. The analyzer features a unique CO detector and can be utilized for a wide range of inorganic materials, including steel, cokes, catalysts, non-ferrous alloys like aluminum, and lithium-ion battery materials.

Flexible Upgrade after Installation

Customer has the option to expand the functionality of the EMIA-Pro system at any time, even after installation, depending on their specific needs:

  • Purifier Unit for carrier gas (for C Analysis) – Enables measurement of ultra-low carbon concentration with high accuracy by eliminating hydrocarbon impurities in the carrier gas.
  • Auto Sampler Unit – Able to accommodate up to 20 positions.
  • Halogen Trap Unit – Helps remove halogen elements in the sample to prevent damage to the device.



Improved Measurement and Maintenance Efficiency

Substantial Reduction in Maintenance

Along with the EMIA-Pro’s cleaning feature, HORIBA has developed a robust design with fewer components for more reliable use and less service requirements.


The latest innovations have enabled the cleaning time for the EMIA Series to be typically half that of our conventional models (patent applied for*). Additionally, the structure around the combustion area has been designed to be as simple as possible, allowing for quick and intuitive maintenance. Specialized skills or knowledge are not required for maintenance work.

Flat design around the crucible stand    


The cleaning efficiency of the EMIA Series instruments has been significantly improved compared to our conventional Carbon/Sulfur analyzers with the use of a unique automatic cleaning mechanism (patent applied for*). This allows users to repeat measurements up to 200 times**, with reduced time required for maintenance and cleaning, without sacrificing measurement accuracy.

High Throughput

The EMIA Series can complete one measurement cycle, measurement-display result-cleaning, in 70 seconds (i.e. about 50 samples/hour).


More Intuitive Software for Easy Operation

Advanced Operation Software

The EMIA Series features its own proprietary operating software, which has been designed with a focus on ease of use, optimizing layout, operating menus, and functions for enhanced user-friendliness.


Enhanced Operator Assistance

Additionally, the software includes a self-diagnostic monitoring feature to assess the status of connected devices, an alarm function, and three navigators to recommend the most suitable conditions for samples, troubleshoot errors, and alert users to perform maintenance. These features improve daily operation and ensure efficient analysis.
