General information

Determination of the Hydrocarbon Index

The hydrocarbon index is defined as the total of all organic substances that can be extracted with hexane, but cannot be adsorbed in Florisil® (magnesium silicate). On a covalent GC column, these elute between n-decane and n-tetracontane and have a boiling range of 175-525 °C. These include heating oils, diesel fuels, kerosene, lubricants and transmission fluids. Petrols are not detected using this method. Carl ROTH offers an extensive range of products for the determination of the hydrocarbon index in accordance with EN ISO 9377-2-Mod. (DIN H53).


According to EN ISO 9377-2-Mod. (DIN H53).

  • Manufactured in accordance with ISO 17034 in an accredited environment
  • Tested in a laboratory accredited to ISO/IEC 17025
  • Ideal for calibration of GC-FID, GC-TCD, GC-ECD, GC-MS, GC-MS/MS, LC-UV, LC-MS and LC-MS/MS
  • With an detailed, batch-related certificate of analysis
