The EMIA-Expert Carbon/Sulfur Analyzer is founded on HORIBA’s extensively reputed non-dispersive infrared (NDIR) technology expertise.
It provides enhanced cleaning efficiency, improved durability, user-friendly software, operability, and maintenance to guarantee effective measurements. Its shortened cycle time expedites users’ development and manufacturing speed.
Advanced Functions for EMIA-Expert
EMIA-Expert consists of advanced functions to identify high-performance analysis besides the standard functions of EMIA-Pro.
High-Performance Purifier Unit for Carrier Gas
Allows measurement of ultra-low carbon concentration with high precision by removing hydrocarbon impurities present in the carrier gas.
High-Performance Heating Filter Unit
Moist samples or those that produce water during analysis can result in a small error in the sulfur analysis. This is a result of the evolved water absorbing the SO2 gas. With the help of the heating filter, the absorption of SO2 by moisture has been avoided, and exact sulfur analysis is ensured.
Features
Long mean time between maintenance (MTBM)
The special newly developed cleaning mechanism (patent pending) helps clear the dust in the furnace, enabling the operator to continue using the EMIA-Expert/Pro without support cleaning for up to 200 measurements.
It relies on sample and measurement condition.

High throughput
EMIA Series could complete one measurement cycle, “measurement-display result-cleaning,” in 70 seconds (that is, around 50 samples/hour).
Fast and easy maintenance
With the latest innovations, the cleaning time for the EMIA Series instruments is usually half of that of the traditional models. The flat design present around the crucible stand and the simple design around the furnace streamlines user access for cleaning.

Advanced operation software
A crucial focus was to guarantee that the EMIA-Expert/Pro Series was “easy-to-use.” The company focused on the layout, operating menus, and functions.
The company has included a self-diagnostic monitor checking ability to hinder the status of the connected device. It is an alarm function that has been expanded to three navigators to enable daily operation.

Measurement of carbon and sulfur in cement
The EMIA 820V C/S analyzer can be used to quantify cement.
Battery evaluation in electrical equipment
Measurement of sulfur in rubber
The addition of sulfur is done in the natural rubber to produce plastic materials. It is essential to quantify the sulfur contained in the rubber to characterize the mechanical and chemical properties of the final product.
Measurement of carbon in ferrosilicon
Ferrosilicon has been added as a deoxidant and also as an alloying element to steel, which needs a unique low-carbon content. The low carbon in ferrosilicon helps reduce the magnetostriction and electrical conductivity of electrical steels.

Sample preparation and sampling methods for the gas analysis of steel
Measurement of carbon and sulfur in copper
Copper, in reddish metal, is ductile, malleable, and is also an extremely good conductor of both electricity and heat. Copper metal finds extensive application in water piping, electrical wiring, and corrosion-resistant parts, either pure or in alloys, such as bronze and brass. Carbon and sulfur are impurities and it is necessary to quantify and check the purity of copper.
Measurement of carbon and sulfur in titanium oxide
In the production of paints and plastics, titanium oxide is utilized primarily and is also used in printing inks, paper, cosmetics, textiles, and food stuff.
Carbon analysis: organic and inorganic carbon in soils
Samples can be made to remove inorganic carbon (carbonates) present in soils.
