Overwhelming Speed - Achieved a 40% Reduction in Typical Analysis Time

"I need to reduce the time I have to spent on measurements. I do not want to make the post-process wait for my result."

HORIBA’ s proprietary sequence algorithm reduces the analysis cycle time compared to our conventional models, by optimizing the gas flow.* _{*patent applied}

Highly Accurate Analyses from ppm to % across a Wide Range of Measurements

"I require my samples to be analyzed with precision, consistency, and reliability."

Proven NDIR Gas Detection Technology

The EMGA Series has NDIR gas detectors developed, designed, and manufactured by HORIBA. Based on detailed design and sophisticated production technology, these detectors are manufactured with close attention to all processes, from the polishing and assembly of components to adjustment and confirmation of stable operation. Our thorough quality control provides stable and highly reliable measurement for an extended period with the EMGA Series. In addition, we have also developed the TCD detector in-house so that these analyzers can demonstrate the best performance.

Please also refer the Measurement Principle page for the details.

Significantly Reduced Both Labor and Consumable Costs

"Less downtime, less running cost!"

Easy Replacement of Lower Electrodes* _{* Patent applied}

With the new design for replacing the chip all you have to do is remove the lower electrode cap to replace the chip, without any special tool. This mechanism reduces the amount of time it takes to approximately 1/10.

New Dust Filter* _{* Patent applied}

With the new mechanism for replacing the dust filter you only need to replace the thin filter inside the filter holder. This has also reduced the filter replacement frequency to 1/10 (replacement required after about 500 measurement cycles).

Significantly Reduced the Carrier Gas Consumption* _{* Patent applied}

The number of measurements that can be performed with one gas cylinder has significantly increased from about 1,400 times to 2,300 times when a 47-liter cylinder is used.

Automation Options

We provide three optional automation units for streamlining your operation for the EMGA Series:
- Crucible Loader: Precise capture and positioning of crucibles by rotary mechanism. Maximum stock: 100 pcs.
- Auto Sampler: Samples and fluxes are automatically loaded (Up to 22).
- Auto Cleaner: Two rotating brushes clean the upper and lower electrodes after each measurement.

Please refer the Automation Options for the EMIA/EMGA Series Elemental Analyzers for the details.

More Intuitive Software for Easy Operation

Advanced Operation Software

The EMGA Series has its original operation software which prioritized ease of use, specifically in optimizing the layout, operating menus, and functions. Additionally, self-diagnostic monitoring was implemented to assess the connected device's status, an alarm function was integrated, and three navigators were expanded to improve daily operation.

Enhanced Operator Assistance

Additionally, the software includes a self-diagnostic monitoring feature to assess the status of connected devices, an alarm function, and three navigators to recommend the most suitable conditions for samples, troubleshoot errors, and alert users to perform maintenance. These features improve daily operation and ensure efficient analysis.

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.

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.

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.

Analysis of Oxygen (O) and Nitrogen (N) in Metal 3D Printer Materials

Stainless steel, Ti, Al, and Cu are commonly used as metal 3D printing materials, and customers have expressed a desire to be able to quickly manage the amounts of oxygen (O) and nitrogen (N) in those materials. For example, if the Ti material contains a large amount of oxygen (O), oxides will be produced, which can lead to defects in the printed part.

Quantitative Analysis of Oxygen in Silicon Wafers

The concentration of oxygen in silicon wafers has a significant impact on their electrical resistance. Therefore, it is crucial to control the concentration of oxygen, even in extremely small amounts, in silicon wafers. However, a challenge arises when analyzing highly doped single crystals. Due to their unique properties and high doping levels, the analysis of oxygen in these samples becomes more difficult. The presence of impurities and dopants can interfere with the accurate measurement of oxygen concentration using FT-IR spectroscopy.

EMGA has been designed for accurate measurements of hydrogen content in different sample types such as ferrous metals, non-ferrous metals, semiconductors or electronic materials. The hydrogen content is extracted by fusion of the sample in inert gas and analyzed by a high sensitivity thermal conductivity detector. It is also possible to avoid fusion and extract hydrogen content in the sample by heating below the melting point. The purpose of this note is to explain when to use fusion or solid extraction, the benefits, the applications and samples.
