Accelerated labor saving through automated analysis

Rich customization options

The EMGA Series features a number of functions required for the automation of measurement, saving labor for measurement work and ensuring safety.

With a “crucible loader” for automatically supplying crucibles, an “auto-cleaner” for automatically cleaning electrodes and disposing of crucibles, an “auto sampler” for automatic loading of samples, and the “automated analysis system,” the analyzers achieve a clean and safe measurement environment that will not dirty the measurement operator’ s hands. In addition, the optimized automation sequence simplifies operation down to just loading the sample and pressing the start button after entering the preset (measurement conditions and sample name).

Principle and Gas flow diagram

The sample is placed in a graphite crucible and the crucible is maintained between the upper and the lower electrode of the impulse furnace. A high current power passes through the crucible to create a high temperature.

The oxide in the sample reacts with the graphite crucible, and is extracted as carbon monoxide (CO), and carried together with the carrier gas. The extracted gas is directly analysed after the dust filter. According to the oxygen concentration, it is determined by CO or CO₂ after pass throw oxidizer (Copper Oxide) with a non-dispersive infrared.

The Hydrogen is determined with a non-dispersive infrared analyser as H₂O after H₂ passes through the oxidizer (Copper Oxide).

The Nitrogen in the sample is extracted as nitrogen gas (N₂) and its concentration is determined by a thermal conductivity detector (TCD).

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.

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 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.

Oxygen and Nitrogen determination in Boron Nitride

This application note will show the relevance of the EMGA-920 to measure high levels of nitrogen while simultaneously determininig low levels of Oxygen with good precision.

Oxygen and Nitrogen determination in Aluminium Nitride

This application note will show the relevance of the EMGA-920 to measure high level of Nitrogen while maintaining the needed precision for Oxygen determination in AIN.

Each year the marketplace sees increasing demands for the analysis of hydrogen contained in various sample materials.

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.
