| Abstract: | Petroleum hydrocarbons have historically been analyzed by a wide variety of test methods. Interlaboratory studies have shown
that standardization of both extraction and gas chromatographic analysis improved interlaboratory variability in hydrocarbon
analysis. The Canadian Council of Ministers of the Environment has required a reference method for use with the Canada-wide
standard for petroleum hydrocarbons. The process for developing and validating this method is described. This method requires
the determination of 4 hydrocarbon fractions, namely, F1 (nC6 to nC10), F2 (>nC10 to nC16), F3 (>nC16 to nC34) and, F4 (nC35+),
using GC-FID or gravimetry. The Tier 1 method was validated in a single laboratory study. This validated method was subjected
to interlaboratory studies to determine its applicability and precision. |
