EXCELLENCE IN ELEMENTAL ANALYSIS

ELTRA becomes ELTRA GmbH imetric analyzer

ELTRA – ELEMENTAL ANALYZERS EXCELLENCE IN ELEMENTAL ANALYSIS Eltra GmbH in Haan, Germany The history of ELTRA GmbH began in 1981 with the development ELTRA has been part of the Verder Group since 2012 and con- of a carbon / sulfur analyzer for metals. Right from the start cus- sistently invests in research and development. With the launch tomer requirements were a priority, ensuring that ELTRA analyzers of the ELEMENTRAC series with powerful ELEMENTS software, are easy to operate, have a long service life and provide reliable and ELTRA offers analyzers for fast and reliable O/N/H and C/S...

ELTRA C/S ANALYZER ELEMENTRAC CS-i For reliable carbon and sulfur analysis in a wide variety of samples The ELEMENTRAC CS-i with a powerful induction furnace is ideally such as metals, ceramics or fuels, ELTRA offers two powerful com- suited for robust analysis of carbon and sulfur in inorganic samples bustion analyzers with IR detection: the ELEMENTRAC CS-i and the such as iron, steel, cast iron, alloys, glasses or ceramics.

ELTRA C/S ANALYZER ELEMENTRAC CS-i The ELEMENTRAC CS-d enhances the ELEMENTRAC CS-i with a resistance furnace to additionally analyze organic samples such as wood, plastics, oils, soils for their C/S content. Induction furnace Resistance furnace Coal, coke, wood, oil Carbides (WC;SiC): Total C Metals: iron, cast, copper, titanium Free carbon in carbides  possible  possible to a limited extent

BENEFITS ELEMENTRAC CS-I I Rapid C/S analysis (40 seconds) I Virtually no sample preparation I Wide measuring range from 1 ppm to 100 % for C and S I Analysis of pins, wires, powders, dust I Simple operation C/S ANALYSIS IN INORGANIC MATERIALS VIA INDUCTION FURNACE

The sample is weighed in a ceramic crucible and accelerators like tungsten are added. The geometry of the sample (e. g. wire, powder, pin etc.) is not essential for a reliable analysis. OPERATION AND ANALYSIS PROCESS The elemental analyzer ELEMENTRAC CS-i measures the carbon and sulfur concentration in predominantly inorganic...

BENEFITS ELEMENTRAC CS-d I Unique combination of induction & resistance furnace I IR path of massive gold I Wide C/S measuring range from 2 ppm to 100 % C/S ANALYSIS IN INORGANIC MATERIALS VIA INDUCTION FURNACE & IN ORGANIC MATERIALS VIA RESISTANCE FURNACE

OPERATION AND ANALYSIS PROCESS STEP 1: LOGGING THE SAMPLE INTO THE STEP 2: WEIGHING THE SAMPLE ELEMENTS SOFTWARE Sample volumes of 50 mg to 500 mg are typical for C/S analysis in a The sample ID is logged into the software and the weight is auto- resistance furnace, depending on the material. The sample is directly matically transferred (see step 2). applied to a boat. Accelerators are usually not required. STEP 4: DATA OUTPUT AND EXPORT The sample is placed in front of the furnace and the measurement 60 to 240 seconds after the analysis has started, the measured is started in the software....

OPTIMUM COMBUSTION IN THE INDUCTION AND RESISTANCE FURNACE The ELEMENTRAC CS-i and CS-d offers intelligent solutions as standard features to provide accurate and reliable measurement of the carbon and sulfur concentrations also in complex sample: cleaning brush features an intelligent lance and combustion management sys- For this purpose, the oxygen flow to be dosed can be applied via and the high oxygen flow of 180 L/hour, solid samples of all types a lance or the chamber to prevent blowing of the sample and are completely decomposed, allowing for determination of the allowing for...

In addition to the integrated features of the ELEMENTRAC CS-d and ELEMENTRAC CS-i, further options are available to increase the efficiency of the carbon / sulfur measurement. Carbon can be determined as total carbon (TC) or in fractions, The induction furnace of the ELEMENTRAC CS-i/CS-d can be i. e. total organic carbon (TOC) or total inorganic carbon (TIC). equipped with an optional automatic sample loader. The standard When combined with the ELEMENTRAC CS-d or CS-i, ELTRA’s module offers 36 crucible positions, the XL model even features 130 TIC module measures the TIC content by...

SPECIAL CONFIGURATIONS OF THE ELEMENTRAC CS SERIES With a broad customer base, ELTRA also has experience in the configuration of analyzers for special applications, such as sulfur analysis of sulfidic ores with very high sulfur content, or C/S analysis of halogencontaining salts. VERSIONS WITH HALOGEN TRAP OR CEMENT CONFIGURATION Some samples release more water during inductive combustion; in case of higher sample volumes this may lead to lower results for sulfur determination, since SO2 is absorbed by the water vapor. An enlarged anhydron trap instead of a metal filter therefore offers...

STANDARD-COMPLIANT OPERATION Regardless of the ELEMENTRAC CS-i or CS-d version, both analyzers meet the requirements of the relevant standards such as ASTM and/or DINENISO. The following standards are supported (among others): Unalloyed steel – determination of low carbon content Nickel, ferronickel and nickel alloys – determination of carbon content Steel and iron – determination of sulfur content Steel and iron – determination of high sulfur content Standard test method for determination of carbon and sulfur (…) in steel, iron, nickel and cobalt alloys Standard test methods for chemical...

The C/S analyzers of the ELEMENTRAC series are controlled by the innovative ELEMENTS software. All essential functions are located in the main window (analyses and results), while less important functions such as application settings or instrument status can be used in other windows. Control and switching of windows is done by PC mouse or function keys. Clear display of measured samples and samples to be analyzed, Comprehensive diagnosis screen for monitoring all relevant tech- analysis graphs and calibration functions in one window nical parameters Clear representation of regression line...
