This is where LECO combustion analysis technology plays a vital role. Known globally for its reliability and precision, LECO Corporation provides advanced instruments that enable laboratories to measure carbon and sulfur quickly and accurately.

As the authorized partner of LECO instruments in India, IR Technology Services Pvt. Ltd. offers cutting-edge solutions that help laboratories achieve accurate elemental analysis with high productivity.

What is Combustion Analysis for Carbon and Sulfur?

Combustion analysis is a widely used analytical method for determining the amount of carbon (C) and sulfur (S) present in a sample.

In this technique, a sample is burned at extremely high temperatures in a controlled oxygen environment. During the combustion process:

• Carbon is converted into carbon dioxide (CO₂)

• Sulfur is converted into sulfur dioxide (SO₂)

These gases are then measured using infrared (IR) detectors, allowing the instrument to precisely calculate the carbon and sulfur content in the original material.

This method is highly reliable and is considered a standard technique for elemental analysis in industrial laboratories.

How LECO Combustion Analyzers Work

Modern LECO carbon and sulfur analyzers follow a highly efficient process:

1. Sample Introduction

A small, accurately weighed sample is placed into a ceramic crucible and loaded into the combustion furnace.

2. High-Temperature Combustion

The sample is burned in an oxygen-rich atmosphere at temperatures exceeding 1350°C, ensuring complete oxidation of carbon and sulfur.

3. Gas Formation

During combustion:

• Carbon forms CO₂

• Sulfur forms SO₂

The gases are carried through the system using a controlled oxygen flow.

4. Infrared Detection

Advanced infrared absorption detectors measure the concentration of CO₂ and SO₂ gases, which directly correlates to the carbon and sulfur content in the sample.

5. Data Analysis

Integrated software processes the signals and provides accurate elemental concentrations within minutes.
