Nonferrous Metals

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.

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.

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.

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.

Fast analysis of microscopic metal particles is an important application for engineering (e.g. engine wear analysis). Micro-XRF scanning and spot analysis of specific fragments identifies their chemical composition.

Polysilicon, the raw material for silicon wafers, requires strict control of carbon content, which affects its conductivity. As higher purity silicon wafers are required, it is important to understand the amount of carbon contained in polysilicon supplied as a material. However, some carbon is present as carbonate and some is attached as CO2, making it very difficult to distinguish between them and analyze the extremely small amount of carbon.

Can we perform quantitative analysis of hydrogen in a titanium alloy to prevent hydrogen embrittlement?

To quickly and accurately quantify the oxygen contained as trace impurities in copper.

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.

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.

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.

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.

No need to sample—simply take your readings directly in place in locations such as reaction vessels Collecting samples during a continuous process can be tedious and even dangerous if hazardous materials are involved.
