Abstract:
Elemental analysis is fundamental in petroleum chemistry. The official method for carbon, hydrogen and nitrogen analysis in petroleum products and lubricants, based on combustion, is described in ASTM D5291. Using the Test Method D levels of 0.01 N% in lubricants can be determined. The FlashSmart Elemental Analyzer permits the simultaneous determination of CHN. The analyzer is equipped with two independent furnaces allowing the installation of two analytical circuits which are used alternatively and automatic through the Multi Valve Control Module. This paper presents CHN data of petroleum products and lubricants to evaluate the accuracy, precision and repeatability of the data.
