1.1 This test method covers the determination of total aromatics and total saturates in additive-free lube basestocks using high performance liquid chromatography (HPLC) with refractive index (RI) detection. This test method is applicable to samples containing total aromatics in the concentration range of 0.2 to 46 mass %.
1.1.1 Polar compounds, if present, are combined with the total aromatics. Precision was determined for basestocks with polars content < 1.0 mass %.
