1 Scope
This section GB/T 18340 specifies the rock and extract crude oil saturated hydrocarbon fraction is analyzed by gas chromatography method, chromatography geochemical parameters
Calculation and precision requirements.
This section applies to crude oil and rock extracts of saturated hydrocarbon components.
Principle 2
Saturated hydrocarbon sample fraction chromatography using a flame ionization detector components have been flowing in the gas chromatograph,
In the area normalization method to calculate the relative percentage of each component, press the appropriate formula to calculate the chromatogram geochemical parameters.
3 Reagents and materials
3.1 Reagents.
a) hexane. AR (by weight distilled) or chromatography;
b) isooctane. AR (by weight distilled) or chromatography.
3.2 Gas.
a) Carrier gas. nitrogen or helium (purity of not less than 99.99%);
b) Gas. Hydrogen (purity of not less than 99.9%);
c) assisting gas. air.

4 Instrument
Gas chromatography. capillary column can be accessed with a split/splitless injection system, temperature programming systems and a flame ionization detector means,
And is equipped with a computer workstation chromatography or chromatography data processing system.
5 Sample Preparation
5.1 Weigh 30mg ~ 50mg rock or crude extract samples overnight with 30mL of n-hexane was dissolved asphaltene precipitation; was treated with 60 ℃
Water bath and concentrated to 1mL ~ 2mL, transferred to a sample containing 2mg 4mg alumina and silica gel column chromatography, using 20mL of n-hexane fraction
Rinsed 4 times the saturated hydrocarbon fraction, a saturated hydrocarbon solution was concentrated with 40 ℃ transferred to stoppered vials small opening in the back.
5.2 split injection mode, the sample is dissolved with hexane back injector; splitless mode, the sample was dissolved with isooctane backward like.
Step 6 Analysis
6.1 Gas Chromatograph open road and circuitry.
