EMIA-Pro Carbon/Sulfur Analyzer

The EMIA-Pro Carbon/Sulfur Analyzer is based on HORIBA’s widely respected expertise in Non-Dispersive Infrared (NDIR) technology.   

It provides durability, enhanced cleaning efficiency, improved user-friendly software, operability, and maintenance to guarantee effective measurements, and its shortened cycle time expedites the development and manufacturing speed of the users.


Long MTBM (Mean Time Between Maintenance)

The newly-developed, unique cleaning mechanism (patent pending) clears the dust in the furnace, allowing the operator to continue to use the EMIA-Expert/Pro without maintenance cleaning for up to 200 measurements.*

*It relies on sample and measurement condition

High Throughput

The EMIA Series is able to complete one measurement cycle, “measurement-display result-cleaning,” in 70 seconds (that is, around 50 samples/hour).

Fast and Easy Maintenance

With the availability of the latest innovations, the cleaning time for the EMIA Series instruments is normally half that of the traditional models. The flat design near the crucible stands and the simple design beside the furnace also ease user access for cleaning.

Advanced Operation Software

A strong focus was to guarantee that the EMIA-Expert/Pro Series was “easy-to-use.” Specifically, the Company focused on the layout, operating menus, and functions.

HORIBA has included a self-diagnostic monitor checking capability to check the connected device’s status, as well as an alarm function and three navigators to enable daily operation.

  • Analysis Navigator

This function uses the suggested best measurement flow and operating conditions based on experience.

  • Troubleshooting Navigator

Automatic diagnosis system and troubleshooting navigator.

  • Maintenance Navigator

Periodic preventive maintenance work navigator by photos and videos.


The customer can extend the system’s functionality anytime based on their requirements, even after installation.

Upgrades include:

  • Carrier gas purifier available for ultra-low concentration carbon measurement
  • Halogen trap unit available
  • Auto-sampler (20 positions)
