1 Scope
This section GB/T 18340 specifies the mass fraction of heavy oil saturated hydrocarbon group components analysis, quantitative calculation and precision
Claim.
This section applies to heavy petroleum fractions (boiling range 205 ℃ ~ 540 ℃) saturated hydrocarbon fraction seven and one kind of aromatic hydrocarbon saturated aliphatic
Quantitative analysis of the components. That no large olefins, aromatics content of less than 5%.
Principle 2
Crude oil is separated by column chromatography, saturated hydrocarbon fraction obtained by direct injection into the mass spectrometer gasification system, the ion source of electronic boom
Strike to give the mixed mass chromatogram saturated hydrocarbon fraction. The mass spectral data of each characteristic peak intensity plus hydrocarbons and post the corresponding inverse matrix system
Multiplication, can be obtained relative content of saturated hydrocarbon group components.
