Carbon/Sulfur Analyzer

High Performance Model: EMIA-Expert 
For expert analyst demanding the greatest accuracy and precision

The EMIA-Expert Carbon/Sulfur Analyzer is based on HORIBA’s widely respected expertise in Non-Dispersive Infrared (NDIR) technology. 
It offers improved the cleaning efficiency, enhanced user-friendly software, durability, operability and maintenance to ensure efficient measurements and its shortened cycle time accelerates your development and manufacturing speed.


Advanced functions for EMIA-Expert

EMIA-Expert has advanced functions to realize high performance analysis in addition to standard functions of EMIA-Pro.

High Performance Purifier Unit for Carrier Gas

Enables measurement of ultra-low carbon concentration with high accuracy by eliminating hydrocarbon impurities in the carrier gas.

High Performance Heating Filter Unit

Samples which are moist or that generate water during analysis may cause a small error for the analysis of sulfur. This is due to the evolved water absorbing the SO2 gas. Using the heating filter, the absorption of SO2 by moisture is prevented, and highly accurate sulfur analysis is guaranteed. 



Segment: Scientific
Manufacturing Company: HORIBA, Ltd.

Long MTBM (Mean Time Between Maintenance)

The unique newly-developed 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 depends on sample and measurement condition


      Before measurement             After 200 measurements


High Throughput

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

Fast & Easy Maintenance

With the latest innovations the cleaning time for the EMIA Series instruments is  typically half of that of our conventional models. The flat design around the crucible stand and simple design around the furnace also simplify user access for cleaning.


Flat design around the crucible stand     

Advanced Operation software

A critical focus was to ensure that the EMIA-Expert/Pro Series was “easy-to-use”. In particular, we focused on the layout, operating menus and functions.
We have included a self-diagnostic monitor checking capability to check the status of the connected device, an alarm function and we have expanded 3 navigators to facilitate daily operation.

* Analysis Navigator 

This function uses the recommended best measurement flow and operating condition based on our experience. 

* Troubleshooting Navigator 

Automatic diagnosis system and troubleshooting navigator. 

* Maintenance Navigator 

Periodic preventive maintenance work navigator by videos and photos. 


The customer can extend the system’s functionality at any time, even after installation, depending upon their needs.
* Auto-sampler (20 positions)
* Halogen trap unit
