VERDER SCIENTIFIC Customer Magazine | Issue 40 ELTRA – Flexible Solutions for Elemental Analysis Precise, Reliable, Flexible

Dear readers, customers and business partners, In this special issue of the VERDER SCIENTIFIC customer magazine “the sample” we present to you ELTRA’s elemental analyzers and give you an overview of the methods and application areas. The concentrations of elements such as carbon and sulfur in metals and fuels are important parameters in many industry sectors which influence not only the product properties (carbon content in steel) but also the process control (flue gas desulfurization). In the field of high performance materials elements such as oxygen and hydrogen need to be measured in...

Construction Materials Experts in Combustion Analysis For more than 30 years ELTRA has been among the leading manufacturers of elemental analyzers. The line of instruments covers a measuring range from a few ppm to 100  and reliably and accurately analyzes organic as well as % inorganic materials. Spectrometric methods For the determination of C, H, N, S, O concentrations in solids, different methods are applied in laboratories and production. Wet chemical methods such as AAS or ICP OES are not only time-consuming and cost-intensive, they are also not suitable for analyzing gaseous sample...

Variety of applications ELTRA analyzers are used in production, quality control, and research and development. There is a very wide array of sample matrices that can be analyzed for their C, H, N, S, O concentrations and thermogravi­ metric parameters with ELTRA analyzers. In order to control the heating value in fuels such as coal, coke, waste, wood, or oil, analysis of the carbon content is necessary. In addition, efficient management of the desulfurization plant requires the control of the sulfur content. Both parameters (and optionally the hydrogen content) can be determined reliably...

Ceramic materials As a result of its thermal characteristics, silicon carbide forms the basis of many mixtures in refractory linings in industrial furnaces. The proportion of SiC can be reliably and accurately determined in the CS-800 indirectly via the carbon content. The content of C, H, N, S and O influences properties such as ductility, corrosion tendency, or brittleness of almost any metal (e.g. steel, iron, copper, titanium, nickel). An effective ONH analysis is possible by means of an electrode furnace (ELTRA ONH series); for CS analysis with an induction furnace, the ELTRA CS-800 is...

Analyzers for C | H | S Determination Wide product selection Individual customization Autoloader available Optional hydrogen analysis High sample weights ELTRA offers a comprehensive product range of high-performance analyzers for the determination of C, H, S. The unique CS-2000 is the only analyzer in the market which features both a resistance furnace and an induction furnace. The CS-2000 provides full flexibility for carbon and sulfur analysis. The induction furnace is suitable for analyzing inorganic sample materials such as iron, copper, steel, titanium or cement while the resistance...

Element combination C = carbon, S = sulfur, H = hydrogen The ELTRA concept: Maximum flexibility for your analysis! ELTRA provides unrivaled flexibility in the configuration of their analyzers, thus being able to respond to customer requirements in the best possible way. Customer-specific configurations include the measurement range as well as the elements to be analyzed. Flexible selection of elements The market mostly offers combined CS analyzers for simultaneous determination of carbon and sulfur. However, if the quality control process requires the determination of only one element, for...

PRODUCT OVERVIEW C | H | S ANALYZERS Carbon | Sulfur Analyzer CS-800 CS-800 Carbon, sulfur Sample materials: The CS-800 determines the carbon and sulfur content in inorganic sample materials. Thanks to high temperatures of up to 2,500  in the °C induction furnace, metals, ceramics, cement and soils are reliably analyzed. The CS-800 can be equipped with up to 4 independent infrared cells with individual measuring ranges. Steel, metal, glass, ceramics, soil Sample preparation: Cutting Carrier gas: Measuring range*: Typical weight: Analysis time: *Extension to 100 % possible by adjusting the...

PRODUCT OVERVIEW C | H | S ANALYZERS Carbon | Hydrogen | Sulfur Analyzer CS-580A & CHS-580A CS-580A | CHS-580A Carbon, sulfur, hydrogen Sample materials: The analyzers of the CS-580A series are available in configurations for the determination of C and S (CS-580A) as well as C, H and S (CHS-580A). They can be equipped with an optional autoloader accepting 36 or 130 samples. For smooth sample loading, the CS-580A series features a vertical resistance furnace with ceramic tube. Temperature regulation and infrared cells offer the same flexibility as in the CS-580 series. Coal, coke, oil,...

The perfect analyzer for each sample Determination of the O | N | H content Flexible configurations and measuring ranges for O, N, H Optional measurement of diffusible hydrogen Powerful 8 kW furnaces Ramping included Extra wide furnace for larger samples ELTRA’s ONH analyzers are highly efficient, flexible and robust. They use inert gas fusion in an impulse furnace and apply temperatures of up to 3,000 °C. Whereas oxygen is detected as carbon dioxide in the infrared cells, nitrogen and hydrogen are determined in a thermal conductivity cell. This method is suitable for analyzing metals such...

Element combination *with optional resistance furnace for the determination of residual hydrogen O = oxygen, N = nitrogen, H = hydrogen Options for ONH analyzers Furnace width In addition to the standard furnace, an extra wide furnace is available for the ONH series which accepts larger samples. Standard Sample size: Crucible volume: Wide version Water or air cooling Efficient cooling is required due to the high temperatures inside the furnace. It is provided by an internal and external cooling cycle to prevent mutual contamination. For the external cooling cycle both water and air cooling...
