Volatile Organic Compounds Detected by BAPI’s VOC Sensor – Application Note


Depending on the source of the information, 5,000 to 10,000 unique Volatile Organic Compounds (VOCs) exist.  BAPI’s VOC sensor reacts to all of them.

VOCs are chemicals that contain carbon and have boiling points below 100°C.  Most can be vapors at room temperature.  In their liquid form many VOCs can contaminate ground water.

Families of VOCs detected are:

  • CO, CH4, LPG
  • Alcohols
  • Ketones. Ketones are solvents.  The best known are Acetone and Methyl Ethyl Ketone or MEK.
  • Organic Acids. Common organic acids are Lactic acid, Acetic acid, Formic acid, Citric acid and Oxalic acid
  • Amines. Amines are derivatives of ammonia. Wikipedia lists 175 compounds as amines, http://en.wikipedia.org/wiki/Category:Amines
  • Aliphatic Hydrocarbons. Aliphatic hydrocarbons are flammable hydrocarbons with little or no odor.  Examples are hexane, paraffin, methane and acetylene.
  • Aromatic Hydrocarbons. Aromatic hydrocarbons are flammable hydrocarbons with a discernible odor.  Examples are benzene, furan, pyridine, toluene, asphaltene and picric acid.
