TL;DR: In this article, the authors propose a column chromatography pressurizer for column chromatographic analysis. But the work is restricted to the separation of the same target component of different samples.

TL;DR: In this article, a method for separating normal paraffin in a petroleum geological sample was proposed, which consisted of the following steps: 1, crushing an SAPO-11 molecular sieve, carrying out granularity screening, activating the screened SAPO 11 molecular sieves in a high-temperature furnace; 2, filling a chromatographic column with the activated sieve; 3, transferring the dissolved saturated hydrocarbon sample into the chromatogram obtained in the step 2; 4, eluting by an eluant to obtain a mixed solution containing normal paraffein

TL;DR: In this article, a method of acquiring a biomarker compound from bio-degraded crude oil was proposed, which includes the following steps: (S) extracting asphaltene from the bio-degraded crude oil; (S2) oxidizing the asphalte to obtain an oxidized crude product; and (S3) esterifying the oxidised crude product with an esterification reagent to obtain the biomarker compounds.

TL;DR: In this paper, a method for separating and enriching gonane and hopane biomarkers in combination with molecular sieves was proposed, comprising the steps of 1) weighing a sample, adding the sample to a fine silica gel packed column, and leaching with n-hexane to separate out saturated hydrocarbons; 2) adding to a ZSM-5 molecular sieve packed column and leach with isooctane, and 3) concentrating the solution obtained in the step 3) to a 10X molecular sieving packed column.

TL;DR: In this paper, a column chromatography pressurization device consisting of a bracket and a branch gas path is proposed for the separation of the same target component of different samples in an oil-gas geochemical laboratory.
