Standard Practice for Optimization, Calibration, and Validation of Ion Chromatographic Determination of Heteroatoms and Anions in Petroleum Products and Lubricants

Importancia y uso:

7.1 Accurate elemental analysis of petroleum products and lubricants is necessary for the determination of chemical properties, which are used to establish compliance with commercial and regulatory specifications.

7.2 Ion chromatography is often used in cases where anion content of the material is desired. Some of the hetero-atoms can be converted by combustion in an oxygen atmosphere followed by aqueous dissolution to convert them into anions before ion chromatographic determination. A number of ion chromatographic ASTM standards issued are listed in Section 2. Of these, the D02, D05, and D16 Committee standards which use ion chromatography are listed in Table 1.
