Greater Accuracy

Proven NDIR Gas Detection Technology

The EMIA-Expert is capable of measuring the concentration of Carbon and Sulfur in samples using the infrared method, which involves combustion in an induction furnace. HORIBA's proven Non-Dispersive Infrared (NDIR) measurement capabilities optimize its range for carbon, from 0.6 ppm to 10.0%, and for sulfur, from 0.6 ppm to 1.0%. The instrument is also equipped with a unique CO detector, and is suitable for a wide range of inorganic materials due to its versatility.

Please also refer the Measurement Principle page for the details.

Standard Accessories for EMIA-Expert

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.
Heating Filter Unit (for S Analysis) - When samples are moist or generate water during analysis, a slight error can occur in sulfur analysis because the evolved water absorbs the SO₂ gas. To prevent the absorption of SO₂ by moisture and ensure highly accurate sulfur analysis, the heating filter unit can be used.

Improved Measurement and Maintenance Efficiency

Substantial Reduction in Maintenance

Along with the EMIA-Expert'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. No specialized skills or knowledge 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.

Measurement of Oxygen Deficiency in Lithium Manganate

Spinel-type lithium manganate (LiMn2O4-σ) is said to change its discharge characteristics due to slight differences in composition caused by oxygen deficiency. The differences in the discharge characteristics of lithium manganate batteries are also observed in the particle size and crystal structure, but attention is also paid to the difference in the oxygen bonding ratio, as samples with less oxygen bonding have poorer discharge characteristics.

Analysis of carbon and sulfur in catalysts in oil refining

Refineries are equipped with desulfurization units to remove sulfur from oil. The changes in Carbon and sulfur content in catalysts before and after the usage is very important to determine the efficiency and performance of developed catalyst. Therefore, a reliable quantitative analysis of carbon and sulfur is important.

Oxygen, Nitrogen, and Carbon Analysis in Nuclear Fuels

From the perspective of ensuring energy security and reducing CO2 emissions, the use of nuclear energy is attracting worldwide attention. A joint declaration was also released by 25 countries setting forth a cooperation policy toward the ambitious goal of tripling the world's nuclear power generation capacity by 2050 compared to 2020 levels. The safety of nuclear fuel as well as the improvement of fuel performance is extremely important, and the content of oxygen, nitrogen, and carbon must be strictly controlled in nuclear material performance.

Analysis of ultra-trace amounts of sulfur in metal

As the steel materials are becoming more sophisticated, such as natural gas or crude oil pipeline, sulfur content is recommended below 0.5 ppm. Hence, more accurate ultra-trace amount sulfur analysis is required. Analysis of trace amount of sulfur in steel materials can be done quickly with the conventional combustion-infrared absorption method, but the problem is that the sensitivity of the detector is insufficient and it can not be measured.

Purity Analysis in Precious Metal Recycling

While precious metals such as Au, Ag, Pt, and Pd are finite materials, they are essential for electronic components and functional materials. Therefore, it is important to separate and extract the necessary precious metals from the final products and recycle them as high-purity precious metals in order to secure resources and reduce costs. Impurities, which must be controlled, include light elements such as carbon, sulfur, oxygen, and nitrogen. For example, Au (gold) used in electronic devices must be at least 99.999% pure.

Measurement of Carbon and Sulfur in Cement

This application note describes the method and conditions to use with the EMIA 820V C/S analyzer to measure cement.

Measurement of Sulfur in Rubber

Sulfer is added in the natural rubber to produce plastic materials. However, it is important to measure the sulfer contained in the rubber to define the chemical and mechanical properties of the final product.

Measurement of Carbon in Ferrosilicon

Ferrosilicon is added as a deoxidant and as an alloying element to steel, that require a special low carbon content. The Low Carbon in Ferrosilicon decreases the electrical conductivity and magnetostriction of electrical steels.

Measurement of Carbon and Sulfur in Copper

Copper in reddish metal, it is malleable, ductile and an extremely good conductor of both heat and electricity. Copper metal is widely used for electrical wiring, water piping, and corrosion resistant parts, either pure or in alloy such as brass and bronze. Carbon and Sulfur are considered as impurities, so it is important to measure and check the Copper purity.

Measurement of Carbon and Sulfur in Titanium Oxide

Titanium oxide are used primarily in the production of paints and plastics and are also used in paper, priniting inks, cosmetics, textiles and food stuffs.

Carbon Analysis: Organic and Inorganic Carbon in Soils

The aim of this application note is to explain the determination of organic and inorganic carbon in soils and how to prepare samples to eliminate inorganic carbon (carbonates) in these soils.
