The Hydrocarbon Oil Index (HOI) is defined as the total amount of compounds which can be extracted from the sample (drinking water, surface water and waste water) with a non-polar solvent having a boiling point between 39°C and 69°C .
In addition, the compounds must not absorb on Florisil® (magnesium sulphate) and must elute between n-decane (C10H24) and n-tetracontane (C40H82) when analyzed by GC using an apolar analytical column.
Certifications: ISO 17025 / ISO 17034. ISO 9377-2.
Delivery information: Delivered with Certificate of Analysis, reference and batch number of source materials.
Packaging: Most articles are packaged in glass ampoules. Certan® bottles provide the advantage of a sealed ampoule with the flexibility of a screw cap bottle or a septum vial. These unique, screw-cap sample containers with a 1,2×28 mm height capillary opening are designed for the storage of volatile samples and reference standards.
