Ships in 1–2 business days
Spec-match guarantee on every lot
Built for production teams
What your process engineer actually checks
Locked, traceable lot chemistry
Every lot ships with a COA documenting PSD, sphericity, flow rate, apparent density, and full chemistry — and a lot number you can trace. Aerospace and medical teams reorder 4+ times without re-qualifying.
Qualified parameters, not just powder
Validated parameter sets for EOS M 290, Renishaw 500Q, SLM 280, and our own AO Metal LPBF ship with the order. Load the profile and hit density on the first build — no parameter-development burn.

About this product
BENEFITS CS‑580A
• Fast & simultaneous elemental analysis of C, H, S, TOC and TIC

• Wide concentration range from 0.005 – 100 %
• High weights possible for elemental analysis of heterogeneous samples
• Optional autoloader with 36 or 130 positions (acid-resistant version available)
• Fast & simultaneous elemental analysis of C, H, S, TOC and TIC
• Configurable for single element (C or S) or multi-element (C/S or C/H/S) analysis
• Wide concentration range from 0.005 – 100 %
• High weights possible for elemental analysis of heterogeneous samples
• Optional autoloader with 36 or 130 positions (acid-resistant version available)
OPERATION AND ANALYSIS PROCESS
Operation of the CHS-580 A elemental analyzer is simple, fast and convenient. The samples are weighed and registered in the software as manual analysis or analysis via autoloader. 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 and SO2 are measured in up to four infrared measuring cells. The results of the elemental analysis can be exported via LIMS, report or text file.
CONFIGURATIONS AND OPTIONS
ELTRA CHS-580 A analyzers can be configured to meet a wide range of customer requirements. C, H, S and 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 CHS-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.
An optional autoloader with 130 crucible positions is available for analyses with high sample throughput.
TYPICAL SAMPLE MATERIALS
The CHS-580 A elemental analyzer is perfectly suited for measuring carbon and sulfur concentrations in matrices such as ashes, building materials, coal, coke, gypsum, limestone, oil, plant materials, rubber, sand, soil, soot, tobacco, waste
FUNCTIONAL PRINCIPLE
In the CHS-580A analyzers the sample is burnt in an oxygen atmosphere at temperatures of up to 1,550 °C. The furnace temperature can be freely selected in steps of 1 °C. The combustion gasses (CO2, H2O, SO2) coming from the furnace pass through a dust filter. After the water vapor is chemically absorbed, the dried CO2 and SO2 gas is detected in the additional infrared cells. Depending on the configuration, it is possible to combine up to four infrared cells with different sensitivities.

Unedited feedback from customers who reorder CHS‑580A.
★★★★★
Same lot 4 times in a row. We stopped re-running parameter sweeps after the second order — density was identical to the first build.

Asked about ferrite content on a Friday. A materials engineer answered Monday morning with actual data, not a sales pitch. That's why we keep ordering.

COA matches the bottle. PSD and flow are exactly what was on the sheet — we run it on a Renishaw 500Q and it hits density on the first try.
