ASTM® D5307 crude oil internal standard has been used in the quantitative determination of diamondoid compounds like adamantane in specific organic solvents like dichloromethane, hexane, carbon-tetrachloride, hexane , heptadecane, hexadecane, pentadecane and tetradecane, using infrared attenuated total reflection spectroscopy (IR-ATR).

Analytes:

Heptadecane 25% (w/w); hexadecane 25% (w/w); pentadecane 25% (w/w); tetradecane 25% (w/w)
