CHNSO Analysis
introduction:
The CHNSO Elemental Analyzer is an advanced analytical instrument that uses flash combustion technology to determine the percentage composition of carbon (C), hydrogen (H), nitrogen (N), sulfur (S), and oxygen (O) in various materials. Its principle is based on burning the sample at high temperatures in an oxygen-rich environment, converting the elements into gases that can be accurately measured using specialized detectors.
Principle of Operation:
1. Combustion: The sample is burned in an oxidizing environment inside a temperature-controlled combustion tube.
2. Conversion of Elements into Gases:
Carbon → Converted into carbon dioxide (CO₂)
Hydrogen → Converted into water vapor (H₂O)
Nitrogen → Converted into nitrogen gas (N₂)
Sulfur → Converted into sulfur dioxide (SO₂)
Oxygen (in some devices) → Determined using additional analytical techniques such as thermal analysis with a CO₂ detector
3. Detection and Measurement: The resulting gases are analyzed using specialized detectors, such as a thermal conductivity detector (TCD) or mass spectrometer (MS).
Significance and Benefits of CHNSO Analysis:
Chemical Composition Analysis: Helps determine the chemical composition of pharmaceutical substances.
Organic Compound Analysis: Used in studying the composition of oil, coal, and geological materials.
Fertilizer Evaluation: Assists in determining the components of agricultural fertilizers.
Food Product Analysis: Used to examine nutritional content and quality.
