LECO Carbon & Sulphur Determination for Steel Plants and Foundries

Carbon and Sulphur analysis with a LECO Infrared Combustion Analyzer

LMATS are pleased to announce the addition of LECO carbon and sulphur analysis by combustion analysis to our range of analytical services.

LMATS has an extensive range of Testing Solutions offering our customers the unmatched capability of applications for the chemical analysis of steel.

LMATS are in the process of being assessed by NATA, Australia to detect Carbon & Sulphur content in steel enabling you to meet and comply with Standards. 

LMATS is a world leader in independent chemical analysis, including carbon and sulphur testing.

LMATS can detect Carbon & Sulfer content in your steel enabling you to meet and comply with various Standards by using a LECO Infrared Combustion Analyzer. 

The infrared absorption method after combustion in an induction furnace is a standard method that enables the analysis of trace amounts of Carbon and Sulphur in metals, ores, ceramics, and other inorganic materials. Many industries can benefit from this technique to accurately determine the carbon and sulphur content of either purchased or manufactured products. This technique relies on the principle that combustion gases CO2 and SO2 absorb infrared (IR) energy at unique wavelengths within the IR spectrum.

LMATS uses the LECO CS744 technology with the ability to accurately analyze carbon content between 0.002% to 6% and sulphur content between 0.002% to 1.75%. The LECO CS744 provides the benefit of an improved construction design and technology that minimizes ambient influence to deliver more reliable results.

This technique requires a small amount of sample for analysis, approximately two grams is adequate. The sample will be combusted in a RF inducted furnace where a stream of oxygen will ensure that all carbon and sulphur oxidize to carbon dioxide (CO2) and sulphur dioxide (SO2) respectively. The combustion gases pass through non-dispersive infrared (NDIR) cells, the device will detect carbon and sulphur and quantify their amounts.

LMATS can deliver the above carbon and sulphur analysis according to the following international Standard and if possible, client in-house specifications.

LMATS applies the LECO infrared absorption method after combustion analysis on the following regular industry applications:

  • Analysis of drillings/burrs from live pipelines for carbon equivalent determination for welding purposes
  • Tiny metallic objects in confectionary, metallic filings in engine oil, or tiny residues from failed parts to assist with failure investigations
  • Confirmation testing for ferrous materials with specified carbon and sulphur limits.

In addition to carbon and sulphur analysis by the infrared absorption method, LMATS has an extensive range of Testing Solutions offering our customers the unmatched capability of applications for the chemical analysis of steel.

LMATS highly qualified staff can arrange for regular process audits for carbon and sulfur analysis of metals.

LMATS highly qualified staff can analyse the carbon and sulphur content for Pre Shipment and Post Delivery inspection before acceptance, for product quality confirmation.

LMATS has the ability to test metal composition by Chemical testing using various methods including, Inductively Coupled Plasma Atomic Emission Spectrometer (ICP-AES) ICP Spectroscopy, Optical Emission Spectroscopy (OES) O.E.S Spectroscopy, Positive Material Identification PMI - XRF Spectroscopy
