Carbon & Sulfur Determination in Steel Plants and Foundries
Different methods are applied to measure C/S concentrations in steel, iron-based products, or in typical foundry products, such as ferro chromium. Among them are multi-element techniques like spectrometry or specialized carbon/sulfur analysis.
Effective Quality Control of Steel and Iron Products with Combustion Analysis
The element concentration of carbon (C), sulfur (S), hydrogen (H), nitrogen (N), and oxygen (O) in iron products, such as steel, have a significant influence on material properties like ductility, brittleness, or hardness. Hence, reliable determination of the C, H, N, S, O contents is a routine quality control task in steel and iron production. This article explores the application fields and advantages of elemental analyzers, which are also known as combustion analyzers, in the steel industry.
Elemental Analysis of Metal Powders and Metal Parts Produced by Additive Manufacturing
Additive manufacturing is becoming an increasingly established production technology. However, as it is still new, the required process steps have not been uniformly defined yet. There are, for example, no industry-wide standards describing the quality control process. Among the metal powders used for additive manufacturing are different types of steel and titanium. To check the quality and purity of these raw materials, suitable processes need to be implemented. The content of various “foreign” elements, for example, should be closely monitored to ensure a high-quality end product.
Fast and reliable C and S determination with elemental analyzers - a useful addition to XRF
Part of the production process of high quality cement is quality control of the raw materials as well as the intermediate and finished products. At each production stage samples are taken, processed and analyzed to determine the chemical composition of the material. For the fast, accurate and reliable determination of carbon and sulfur elemental analyzers using combustion technology are a useful addition to XRF analyzers. Apart from size reduction no further sample preparation is needed for analyzing a sample with an elemental analyzer. In contrast to XRF analysis the element content of carbon and sulfur can be measured from the ppm range up to 100 % and the results are usually obtained within 60 to 120 seconds.
O/N and C/S Analysis of Battery Components
Regardless of the dimensions of a battery, its application or its configuration as primary (not rechargeable) or secondary battery (rechargeable), a chemical analysis for carbon, sulfur, oxygen or nitrogen may be required for single components. A reliable and precise measurement of C/S and O/N in selected samples over a wide concentration range is possible with elemental analyzers like the ELEMENTRAC CS-i and ONH-p 2.
O/N/H Analysis in Raw Materials for Aircraft Components
Raw materials used in aircraft components need to fulfill a number of requirements. To verify the requested material properties and ensure maximum safety, each component is submitted to thorough testing. Part of the quality control process involves testing of mechanical properties, like tensile strength, or elasticity but also the determination of the chemical composition. One important part of chemical analysis of materials used in the aerospace industry is always the measurement of the gases oxygen (O), nitrogen (N) and hydrogen (H) which have a significant influence on the material properties.
Quality control of cement
Elemental analysers based on combustion technology are a useful addition to XRF analysis for the quality control of cement and related products, ensuring fast, precise and reliable determination of carbon and sulphur. With its offering of analyzers using resistance or induction furnaces or both, ELTRA covers a wide range of applications for C and S determination in organic and inorganic samples. The product range is ideally suited to the variety of analytical applications in a cement plant.
Standard-compliant element analysis of silicon carbide and mixtures containing silicon carbide with combustion analyzers
Elemental analyzers are important tools for quality control of a wide range of products. A variety of matrices, such as ceramics, coal, steel or soil, can be analyzed for their element concentrations with different types of instruments. The product range of Eltra GmbH, located near Düsseldorf, Germany, comprises analyzers for C, H, N, S, O and thermogravimetry which allow for the standard-compliant determination of carbon in various chemical bondings, as well as oxygen and nitrogen in SiC and in materials containing SiC. The requirements which have to be fulfilled for a standard-compliant analysis may, however, vary greatly, depending on the desired parameters.
Möglichkeiten der normgerechten Elementanalyse von Siliciumcarbid und Siliciumcarbid enthaltenden Mischungen mit Verbrennungsanalysatoren
Elementanalysatoren leisten einen wichtigen Beitrag zur Qualitätssicherung vieler Produkte. Unterschiedlichste Matrizes wie Keramiken, Kohle, Stahl und Böden können mit verschiedenen Instrumenten auf ihren Elementgehalt hin untersucht werden. <b>Die ELTRA GmbH mit Sitz in Haan bietet mit ihren Analysatoren für C, H, N, S, O und Thermogravimetrie die Möglichkeit, Kohlenstoff in unterschiedlichen Bindungsformen sowie auch Sauerstoff und Stickstoff in SiC und SiC enthaltenden Stoffen umfassend und normgerecht zu bestimmen.</b> Je nach gewünschtem Parameter sind jedoch sehr unterschiedliche Anforderungen für eine normgerechte Analyse zu erfüllen.
