Embodiment approach 1

[0041] Embodiment one single chromatography column component separation preparation instrument

[0042] Based on the single chromatography column component separation and preparation instrument of the first embodiment, such as figure 1 As shown, it includes: a chromatographic column 10 ; a sealing device 20 ; a pressurizing device 30 ; a sample input device 40 ; a reagent adding device 50 ; a component collecting device 60 ; a control device 70 . The connection relationship between these components and their respective functions are respectively stated as follows.

[0043] The control device 70 is at least connected to one of the sample input device 40 , the reagent adding device 50 , the pressurizing device 30 and the component collecting device 60 , and controls the connected equipment to automatically complete corresponding actions.

[0044] Under the action of the control device 70, the sample input device 40 inputs the sample to be separated into the chromatographic colu...

Embodiment approach 2

[0049] Embodiment 2 Multi-layer Chromatographic Column Component Separation Preparation Instrument

[0050] The component separation preparation instrument based on the second embodiment of the present invention includes a plurality of chromatographic columns for simultaneously performing component separation on multiple samples to be separated (such as crude oil samples from different oil fields), and each sample to be separated contains multiple kinds of components.

[0051] figure 2 For two samples to be separated containing three components respectively ( figure 2 The situation of component separation in sample 1 and sample 2) is taken as an example to illustrate the connection relationship between the components of the component separation preparation instrument based on multiple chromatography columns.

[0052] From figure 2 It can be seen from the figure that the structure of the component separation preparation device is, which includes:

[0053] Chromatographic...

Embodiment

[0060] The following is a brief description of the process of separating the three components of saturated hydrocarbons, aromatics, and colloids in crude oil by using a single chromatography column component separation preparation instrument as an example (note: before using the chromatography column for separation, first Add n-hexane to the crude oil sample to separate the asphalt, and then use the component separation and preparation instrument of this application to separate the other three components).

[0061] Using dichloromethane + n-hexane, absolute ethanol, and chloroform as the three separation reagents, the specific steps of petroleum separation and preparation are analyzed:

[0062] (1) Packing of the chromatographic column, first add the stationary phase (chromatographic silica gel 3g, alumina 2g, the two substances act as carriers to adsorb and desorb the separation reagent) into the chromatographic column, and immediately add 6mL Wet the chromatographic column w...

Abstract

The invention relates to a component separating preparation instrument including: a chromatography column, a sealing device, a sample input device, a reagent adding device, a pressure device and a component collection device. A sample for separation is loaded into the chromatography column by the sample input device, leaching solvents which are reagents for separation are successively added into the chromatography column by the reagent adding device and the pressure device, and separated components are collected by the component collection device. Compared with a traditional separation device, the component separating preparation instrument substantially improves the separation speed, enables separation accuracy to be not affected by a skill level of an operator, and has good repeatability. Because all processes of separation operation are carried out in a closed environment, the harm of poisonous, harmful, carcinogenic reagents to the health of the operator is reduced, and the environmental pollution is reduced.

Description

technical field [0001] The invention relates to a separation and preparation instrument, in particular to an instrument for separating and preparing components of different mixtures containing multiple active ingredients. Background technique [0002] In petroleum, chemical industry, biology, medicine, environmental protection, food and other fields, it is often necessary to separate and prepare a certain type of compound in order to achieve the purpose of further accurate analysis of the instrument. [0003] The components contained in petroleum are very complex and vary according to the place of origin. The chemical composition of petroleum is closely related to its physical properties. The characteristics of the two are of great significance to the study of oil formation, migration, accumulation, preservation, secondary transformation and distribution, and to evaluate the industrial quality of oil. Petroleum contains four race components of saturated hydrocarbons, aroma...
