Abstract
The use of a gas chromatograph employing a 36-m SE-30 glass SCOT column with dual flame-ionization—nitrogen—phosphorus detection (NPD) for oil identification is described. A rapid extraction and concentration procedure for increasing the size of NPD peak patterns from oils of low N-content and eliminating spurious peaks due to excess aliphatic hydrocarbons is presented. Studies of artificially “weathered” oils indicate that the gas chromatographic—NPD fingerprint of light distillate oils is lost, but that of heavier oils is unchanged. The capabilities and limitations of the gas chromatographic—NPD fingerprints for oil identification are illustrated with reference to real spill case samples.
