(Romero-Lopez et al.
A solution of tetracosane
in carbon disulfide was injected into the instrument to determine if this compound could be sampled in the exhaust.
Aliphatic unbranched and branched long chain hydrocarbons from dodecane to tetracosane
form the last important compound group.
are widely used in fuel oils and as anti-corrosive agents in lubricating oils and solid alkanes (octadecane nonadecane eicosane heneicosane tricosane tetracosane
heptacosane octacosane etc.
Sterol quantification was performed using tetracosane (Sigma Aldrich) as the internal injection standard.
Only three long chain alkanes were detected (tetracontane, tetracosane, heptacosane) which were found in some marine and river sampling stations without revealing a spatial pattern, but showing some consistency with the presence of other terrestrial biomarkers (data not shown).

A mixture of saturated alkanes, such as tricosane, tetracosane

The major hydrocarbons were ranging from undecane (C11) to tetracosane
