Halogen analysis in laboratory
Would you like to analyze and determine the halogen content of your samples?
What is a halogen?
Halogens are chemical elements in Group 17 of the periodic table, including fluorine, chlorine, bromine and iodine. These elements are commonly analyzed in various materials and products because of their potential to cause corrosion and their environmental impact.
A halogenated compound is a chemical substance in which one or more halogens are bonded to other elements.
List of halogenated compounds to be analyzed
Halogenated compounds are used in a wide range of industrial applications, including as solvents, cleaning agents, flame retardants and refrigerants, as well as in the manufacture of pesticides and plastics.
Halogenated compounds are commonly analyzed in:
Organic compounds in which one or more hydrogen atoms have been replaced by halogens (fluorine, chlorine, bromine or iodine). They are often used as solvents and cleaning agents.
- Carbon tetrachloride (CCl₄)
- Methylene chloride (CH₂Cl₂)
- Chloroform (CHCl₃)
- Tetrachloroethylene (C₂Cl₄)
Organic molecules containing halogens. They are commonly used as pesticides and flame retardants.
- DDT (Dichlorodiphenyltrichloroethane)
- PCBs (Polychlorinated biphenyls)
- Bromodichloromethane (CHBrCl₂)
- Hexachlorobenzene (C₆Cl₆)
Compounds in which carbon atoms are bonded to fluorine atoms. Fluorinated polymers, such as Teflon, are used for their non-stick properties and chemical and thermal resistance.
- Teflon (PTFE - Polytetrafluoroethylene)
- CFCs (Chlorofluorocarbons)
This category includes various halogen-containing compounds used in organic synthesis, pharmaceutical manufacturing, and as fumigation and sterilization agents in agriculture.
- Methylene iodide (CH₂I₂)
- Ethylene bromide (C₂H₄Br₂)

Why check the halogen content (fluorine, chlorine, bromine and iodine)?
Materials are sensitive to halogens mainly because of the high chemical reactivity of halogens. These elements can interact with materials, triggering chemical reactions that lead to corrosion, degradation and embrittlement of structures.
For example, halogens can cause the rapid oxidation of metals, thereby weakening their integrity. In polymers, halogens can also cause depolymerization and deterioration of mechanical properties, compromising the durability and safety of materials used in industrial applications.
Checking halogen content therefore helps prevent material failures. In addition, many industrial sectors, such as aerospace, automotive and nuclear energy, require specific halogen levels to comply with safety standards.
In what contexts should halogens be analyzed and quantified?
Whether you work in aerospace, plastics manufacturing, automotive, fine chemicals or energy, these analysis may be relevant to you.

Which industries use fluorocarbons and fluorinated polymers?
Fluorocarbons and fluorinated polymers, such as Teflon and CFCs, play a key role in various industries. The aerospace industry uses Teflon parts for their non-stick properties and resistance to high temperatures. The automotive industry applies Teflon coatings to improve the durability and performance of parts. CFCs are used as refrigerants in refrigeration systems, although their use is now limited due to environmental concerns.
Which industries use halogenated compounds?
Other halogenated compounds, such as methylene iodide and ethylene bromide, are also important. In the chemical industry, methylene iodide is used in organic synthesis to produce various chemical compounds. Ethylene bromide serves as an intermediate agent in the pharmaceutical industry for the production of medicines. In addition, the agricultural industry uses these compounds for fumigation and soil sterilization, thereby ensuring optimal growing conditions.
What are the differences between halogens, halides, and halogenated compounds?
Halogens are chemical elements in group 17 of the periodic table, such as fluorine (F), chlorine (Cl), bromine (Br), and iodine (I). They are highly reactive elements. Halogens must be analyzed to prevent corrosion and comply with safety standards.
Halides are compounds formed when halogens bond with other elements, generally metals. One example is sodium chloride (NaCl). Halides require analysis to prevent undesirable reactions in materials and products.
Halogenated compounds are molecules in which halogens are bonded to carbon atoms or other elements in organic or inorganic compounds, such as tetrachloromethane (CCl₄) or PCBs. Halogenated compounds must be analyzed to detect toxic substances and ensure the safety of industrial products.
