What your QC lab actually checks
Simultaneous C/S over a wide range
Combustion in a resistance furnace adjustable to 1,550 °C, with up to four solid-state infrared cells, determines carbon and sulfur simultaneously from 0.005 % up to 100 % in 60–120 seconds. Single-element (C or S) or combined C/S configurations, plus TOC to DIN EN 15936 and an optional TIC module, cover organic and inorganic matrices from one bench.

The ELTRA CS-580A is a combustion analyzer for the simultaneous determination of carbon and sulfur in organic and inorganic samples. The sample is burned in an oxygen atmosphere in a resistance furnace adjustable up to 1,550 °C in 1 °C steps; the combustion gases (CO₂, SO₂) are dried and measured in up to four solid-state infrared cells. It covers 0.005–100 % as a single element (C or S) or a combined C/S configuration, accepts 50–500 mg sample weights, and supports TOC to DIN EN 15936 plus an optional TIC module.
Why QC and materials labs choose the CS-580A
Simultaneous carbon and sulfur analysis over a wide concentration range, from trace to 100 %.
Simultaneous C/S in 60–120 s
Fast, simultaneous determination of carbon and sulfur over 0.005–100 % — configurable for a single element (C or S) or combined C/S analysis.
Up to four infrared cells
Combine multiple solid-state IR cells with different sensitivities, plus a gold IR path, for a wide dynamic range on both trace and very high sulfur levels.
TOC & TIC ready
Runs TOC analysis to DIN EN 15936 with an optional acid-resistant autosampler, and adds an optional TIC module for total inorganic carbon.
High-throughput autoloader
An optional 36- or 130-position autoloader — including an acid-resistant version — keeps high sample volumes running with minimal operator attention.
How Additive Plus supports it
A configured, installed analyzer with a carbon/sulfur method dialed in on your samples.
Configure to your samples
We spec the C/S configuration, IR cells, TIC module and autoloader to your matrix and concentration range before it ships.
Install & train
Factory-trained engineers install the analyzer, connect oxygen, air and the PC/balance, and train your team on weighing and analysis.
Method & QC support
We help build the SOP — calibration with standards, blank control, TOC/TIC method and a repeatable carbon/sulfur baseline.
