Saturates/aromatics/polar fractions and whole oils

APT is proud to offer state of the art facilities for GC, GC-MS and GC-MS/MS to assess saturates/aromatics/polar fractions and whole oils.

Gas chromatography (GC)

GCs provide detailed information on the saturates fractions and whole oils. Measurements such as Pristane/Phytane, Pristane/nC17, Phytane/nC18 and CPI ratios are derived to allow you to better characterise your fluids. GC of whole oils also includes high resolution of gasoline range components and a full suite of industry standard parameters.


Gas chromatography - Mass spectrometry (GC-MS)

GC-MS analyses are performed on saturates/ aromatics/polar fractions and whole oils. Quality assurance is achieved via regular analysis of standards, as specified by NIGOGA (http://www.npd.no/engelsk/nigoga/default.htm)

Three main types of analyses are routinely available:

  • High resolution GC-MS (HR-GC-MS-SIR)
  • Low resolution GC-MS (LR-GC-MS-SIR)
  • Low resolution GC-MS-MS

Gas chromatography - Mass spectrometry / Mass spectrometry (GC-MS/MS)

GC-MS/MS provides chromatograms that are free from the type of interference that can obstruct evaluation of parameters from normal GC-MS analysis. This can be especially useful for compound classes that are present in very low abundance.
