CS Analyzer – LECO CS-744
| Investigation method | Combustion analysis with subsequent spectroscopic detection of carbon and sulfur |
| Abbreviation | CS Analyzer |
| Device type and equipment | High-temperature combustion analyzer with infrared (IR) detection for carbon and sulfur |
| Functional principle | The sample is combusted in an oxygen atmosphere at high temperature. Carbon and sulfur are oxidized to CO₂ and SO₂, which are quantified by infrared absorption detectors. |
| Elements analyzed | Carbon (C), Sulfur (S) |
| Typical applications | Metals and alloys, ores, minerals, cement, refractory materials, battery materials, and other inorganic solids |
| Detection limit | Carbon and sulfur: approx. 0.002 mg (absolute) |
| Measurement range | From trace levels up to high percentage concentrations (method-dependent) |
| Requirements for sample | Approx. 1 g solid sample (powder or granulate); homogeneous and dry |
| Sample throughput | Rapid analysis, typically a few minutes per sample |
| Accuracy and precision | High accuracy and repeatability due to controlled combustion and IR detection |
| Calibration | Calibration using certified reference materials (ISO17034) |
| Accreditation / Certification | ISO17025 |
| Advantages | Robust method, fast analysis, wide measurement range, reliable results for routine and quality control applications |
With our LECO CS analyzer, we offer precise and reliable determination of carbon and sulfur for a wide range of materials.
Typical customer questions we address include:
- Mineral samples: Determination of total carbon and sulfur for raw material characterization, process control, and quality assurance (e.g. sulfide/sulfate content, carbonaceous impurities).
- Black mass from battery recycling: Quantification of residual carbon and sulfur to support process optimization, material classification, and evaluation of recycling efficiency.
- Steel: Accurate measurement of carbon and sulfur for grade verification, compliance with specifications, and metallurgical process control.
Our CS analysis provides fast results across a wide concentration range, from trace levels to high contents.
