The analyzers of ELTRA’s C(H)S 580 A series determine the concentrations of carbon, hydrogen and sulfur in predominantly organic samples via combustion in a ceramic resistance furnace at temperatures up to 1550 °C, followed by detection in infrared measuring cells.
Configuration
The ELTRA C(H)S 580 A provides fast, accurate, and robust carbon, hydrogen, and sulfur analysis over a wide concentration range from the lower ppm range up to 100 %. Depending on the application, the analyzers can be configured with different measuring cells. The robust design of the C(H)S 580 A series also allows the analysis of acidified samples (TOC measurement)
Benefit
- Fast & simultaneous determination of C; H; S
- Configurable as C; S; C/S or C/H/S analyzer
- Wide concentration range from 0.005 – 100 %
- High weights possible for analysis of heterogeneous samples
- Optional autoloader with 36 or 130 positions (optional acid-resistant
Operation
Operation of the C(H)S 580 A is simple, fast, and convenient. The samples are weighed and registered in the software as manual analysis or analysis via autosampler. Typical sample weights are between 50 and 500 mg. After starting the analysis, the sample is introduced into the furnace, and the combustion gases CO2; H2O, and SO2 are measured in up to four infrared measuring cells. The measurement results can be exported via LIMS, report, or text file.
Typical Sample Materials
Fuels (coal, coke, oil, secondary fuels); soil (TC and TOC); ores; construction materials
Configuration and Options
ELTRA C(H)S 580 A analyzers can be configured to meet a wide range of customer requirements. C; C/S; C/H/S configurations are available with up to 2 infrared cells for each element to cover a wide working range. Robust measuring cells for the reliable determination of sulfur in very high concentrations are also available. The ELTRA C(H)S 580 A series is perfectly equipped for TOC analysis according to DIN EN 15936 with optional acid-resistant autosamplers, as well as the optional TIC module

The Eltra Application Laboratory
For many common samples, such as ores or ceramics, no standards are published regarding carbon and/or sulfur analysis by combustion analysis and IR detection. To guarantee a safe and reliable measurement, the ELTRA laboratory in Haan is available for application advice and free trial measurements with all ELTRA analyzers. By participating in round-robin tests (e.g. ASTM Powder Metallurgy) and in the certification of reference materials (e.g. ECRM 268-1; ECRM 049-1), a consistently high analysis quality is guaranteed
About Eltra
The development of the first carbon and sulfur analyzer in 1981 marked the beginning of ELTRA’s success story 40 years ago. From day one, the focus was on the design of analyzers for the precise determination of C, H, N, O, S element concentrations in solids.
Over the years, the product portfolio was further expanded and refined, for example by adding thermogravimetric analyzers in 2007. Our goal has always been to design combustion analyzers which are characterized not only by high precision and detection sensitivity but are also robust enough to provide reliable measurement results under rough conditions. The new generation of ELEMENTRAC analyzers impressively combines this claim with state-of-the-art technology and ease-of-use. The excellent price-performance ratio of our products together with our fast and reliable technical service helped ELTRA to continuously gain market share over the past four decades. Today, we are represented in more than 80 countries by a broad sales & distribution network.
In 2012, ELTRA became part of the VERDER Group and was integrated into the Scientific Division, which is home to renowned companies from the laboratory & analytical sector, including Retsch and Microtrac. Under the new management, substantial investments were made in new products and services for C/H/N/O/S elemental analysis and macro thermogravimetry. Customers in quality and analysis laboratories as well as research departments appreciate the speed, precision, and ease of use of our analyzers.
Our past experience and achievements motivate us to continue developing new analyzers. Securely positioned for the future, we will integrate new technologies into our portfolio which will allow us to conquer new markets over the next 40 years.
