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

Advanced functions

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

Long 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

Flat design around the crucible stand

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.

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.

Other features

High Throughput

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

Troubleshooting Navigator 

Automatic diagnosis system and troubleshooting navigator

Analysis Navigator

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

Maintenance Navigator
