Combustion Analysis

Combustion analysis is a powerful technique used to obtain the elemental composition of organic and inorganic materials. The laboratory analyzers can provide highly sensitive and reliable carbon, hydrogen, oxygen, nitrogen, and sulfur measurements. A known weight sample is burned in a high-temperature, high oxygen environment in the laboratory. The combustion gases obtained are filtered and purified. A sequence of absorption traps and infrared cells detect and quantify total as well as fractional elemental concentrations. Total organic carbon (TOC) and total inorganic carbon (TIC) are also measured after sample acidification. The operating temperature could be as high as 3000 °C and varies depending on the furnace used. The infrared cells are customized based on the type of analyzer. Combustion analysis done in testing labs can detect concentrations of C/S and O/N/H as low as 1 ppm. Combustion analysis is an extremely reliable technique for elemental analysis of solid samples, especially at low concentrations.

Laboratory experts at Infinita Lab assure the best regular product reliability testing to ensure your product performs as expected, reduces warranty costs, and provides satisfaction.

Combustion Analysis Common Uses

  • Precise measurement of C/S/N/H/O concentrations in bulk, powders, granules, or other solid samples
  • Test inhomogeneous samples
  • Check carbon impurities in materials
  • Fractional analysis
  • Total organic and total inorganic carbon measurements (TOC and TIC)
  • The total, free and bound carbon content for ceramics
  • The surface carbon content of metals and alloys


  • High sensitive and highly reliable test data
  • Detection range 1pp to 100%
  • Any solid sample type
  • High sample weights up to several grams
  • No sample preparation required


  • Only solid sample analysis
  • Limited to elemental analysis of C, O, H, N, S

    FAQs on Combustion Analysis

    Where can I do combustion analysis of materials?

    We provide combustion analysis for determining the elemental composition of organic compounds to suit all your needs.

    What is combustion analysis of materials?

    Combustion analysis is a standardized method used to determine the elemental composition of a pure organic compound by combusting the sample. The number of moles of each combustion product is determined which is then used to calculate the empirical formula of the original compound. 

    What is combustion analysis used for?

    Combustion analysis is used for obtaining the elemental composition of an organic compound. It provides sensitive and reliable measurements of carbon, hydrogen, oxygen, nitrogen, and sulfur. It is a reliable tool used to obtain the total organic content of materials (TOC), surface carbon content, and fractional analysis.

    What are the three methods of combustion?

    The three methods of combustion are rapid combustion, spontaneous combustion, and explosive combustion.

    What are the 3 main products of a combustion reaction?

    The three main products of a combustion reaction are cabon dioxide, water, and energy.

    What are the 3 main components in combustion?

    The three main components in combustion, also known as the “fire triangle”, are heat, fuel and oxygen.
