The distribution ranges of boiling points of petroleum fractions provides information about the composition of the raw and related materials to the refined petroleum products. The simulated distillation methods require less time and less operator intervention compared to physical methods of distillation, improving reproducibility and repeatability, and allowing better accuracy and speed. The solution presented here offers a unique opportunity for a fast, robust, reliable, accurate and precise analysis with ASTM D2887. The ASTM D2887 standard is designed to determine the distribution range of boiling points of petroleum products and fractions which have a boiling point more or equal to 545°C using a calibration mixture between C5-C44.
All stages of sample preparation (dilution, mixing, heating and agitation) can be automated available through a manage sample preparation system customized composed by a type PAL system and a special software control. Therefore, the offered solution gives higher safety in the laboratory as a result of the automation, management of small volumes of solvent, a controlled heating and stirring in 2 mL vials.
The method of analysis consists in a gas chromatograph based on Low Thermal Mass (LTM) technology. This technology uses a resistive heating mode, allowing programming very fast temperature ramps and extremely fast column cooling. This technology allows carry out analysis of Reference Gas Oil (GRO) in a time of 2.5 min, about 6-7 times lower than conventional GC. The PAL automatic injection coupled to gas chromatograph performed the injection according to ASTM D2887. The system is designed for determining ranges of petroleum products up to boiling point 538 °C (C5-C40) or 545 °C (C5-C44), with a difference between the initial boiling point (IBP) and final boiling point (FBP) bigger than 55 °C. Compounds with higher boiling points or those who adhere to the chromatographic column permanently, will not be detected.
