A high performance liquid chromatography (HPLC) method for assessing the compositions of crude oils and fluid inclusion oils is described. The necessary increase in instrumentation sensitivity was accomplished using a narrow bore Waters Spherisorb column with 5 μm particle diameter. This HPLC method has advantage over the Iatroscan TLC–FID technique previously described as the
