IP 469: Determination of saturated, aromatic and polar compounds in petroleum products by thin layer chromatography and flame ionization detection

Overview:

This standard specifies a procedure for the determination of saturated, aromatic and polar compounds in petroleum products and feedstocks having an atmospheric boiling point of 300 EC minimum at 5 % recovered sample. The standard classifies the output into four compound-types designated as saturates, aromatics, polars (I) and polars (II) and quantifies these. The test method is applicable to both distillate products and feedstocks and those containing residues from processing. A broad chemical compound type breakdown is increasingly being sought as a precursor to more detailed analysis for environmental considerations
