Why this test matters

Small variations in carbon and sulphur can have a major impact on material behavior. Carbon sulphur analysis helps companies ensure consistent composition, mechanical properties, and process reliability. It reduces the risk of brittle failure, corrosion issues, or non-compliance with specifications. This test is widely used in metals, alloys, powders, ceramics, and process materials across industries such as steelmaking, automotive, aerospace, energy, and manufacturing.

How the test works

The test determines carbon and sulphur content by combusting a prepared sample in a controlled oxygen-rich environment. The high temperature causes carbon and sulphur to oxidize into measurable gases. Sensors detect and quantify these gases to calculate precise concentration values. Key parameters include combustion temperature, sample mass, calibration method, and detection range.

What you learn from this test

The test provides exact carbon and sulphur concentrations, typically expressed as weight percentages or parts per million. These results help verify material specifications, control production processes, and assess compliance with standards. Companies use the data to fine-tune formulations, improve material performance, and support quality documentation or certification.

Frequently Asked Questions

We don't stop at a "non-compliant" label. Our diagnostic experts can help identify the root cause and advise on next steps, so a failed test becomes a starting point for a fix, not a dead end.

No, not all of them. Accreditation is granted per specific test method and standard, not for the lab as a whole. Some of our tests are carried out under BELAC accreditation, others follow international standards or our own validated methods without being part of the formal accreditation scope. Where relevant, this is indicated on the individual test page.
