Algemene informatie

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).

Standards

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


Salts for Analysis

Our salts for analysis are manufactured under strict production guidelines. Analytical purity and best quality reliably characterize each batch. Salts in p.a. quality made by Carl ROTH meet the high requirements for reproducible results. Most of our salts are additionally specified according to international standards like ACS and ISO.

Salts


Desiccants

Desiccants can absorb water and bind it chemically (reversibly or irreversibly) or physically. The main desiccants can be subdivided into four categories:

  • non-renewable chemical desiccants
  • renewable chemical desiccants
  • silica gels
  • molecular sieves
