Abstract
The utility model discloses a chromatographic column which comprises a visual column body and a dropping pipe arranged on the lower end of the visual column body. A vacuum-pumping port is formed in the lower end of the visual column body. Real-time visualization of a column chromatography isolation process is achieved by the chromatographic column, certain pressure can be supported, and resin can be pumped to be dry and solid.
Description
Technical field
The utility model relates to kind of a visual chromatographic column that is applied to the separation of mixed chemical component, purifying.
Background technology
At present, the separation and purification of the composition of multiple compounds, natural products and Chinese medicine mainly is to adopt column chromatography, uses chromatographic column, realizes by the column chromatography process.Traditional column chromatography is the top that mixing cpd is placed on glass column post bed, make the eluant, eluent (mobile phase) of mixed solvent composition under Action of Gravity Field, by the vertical glass column of absorbent media material (fixedly phase) is housed, separate and obtain each purer product (sterling), its principle is: because each component is different with the affinity of mobile phase to fixing phase in the chromatographic column in the mixing cpd, so the character according to mixing cpd is selected suitable fixedly phase and mobile phase, can reach the purpose that each component is wherein separated as far as possible, the product that separates is collected into respectively in each receiving flask in the pillar outlet, then, identify the chromatographic solution of collecting in each receiving flask, merge and concentrated each identical chromatographic solution according to qualification result, obtain each sterling.Chinese patent discloses CN201120198679.1 Novel UV transmissible chromatographic column, comprises the frosted mouth on cylinder, cylinder top, the minim pipette of cylinder lower end, and the cylinder of chromatographic column is by can uv-transmitting material making.Chinese patent also discloses CN201120012910.3 visible fluorescent chromatographic column, it is characterized in that, described visible fluorescent chromatographic column is provided with the quartz glass cylinder that consists of and the joint that is installed in the cylinder end by saturating ultraviolet spectra, be filled with fluorescence or luminous filler in the described cylinder, described cylinder two ends are provided with the filter that prevents that described fluorescence or luminous filler from revealing.But the chromatographic column that generally uses now be by simple glass, common high-boron-silicon glass, can uv-transmitting material or thoroughly the quartz glass of ultraviolet spectra make, all exist and can not bear too large pressure defective.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of can bearing certain pressure, resin can be drained real chromatographic column.
The utility model is achieved by the following technical solution:
Chromatographic column comprises the minim pipette that visual cylinder, visual cylinder lower end arrange, and described visual cylinder lower end also is provided with and vacuumizes interface.
Be provided with a layer sieve plate in the described visual cylinder.
The described interface that vacuumizes is arranged on the vacuum-pumping tube, and described minim pipette is arranged in the vacuum-pumping tube.
The utility model compared with prior art has following beneficial effect:
1, realized the real-time visual of column chromatography for separation process after, can also be in real time according to the separating effect that observes, the mixtures of eluents (mobile phase) of different proportion is selected and adjusted to real-time online, thereby can immediately revise column chromatography separating effect, really make column chromatography process implementation real-time online visualized operation, not only column chromatography for separation efficient can significantly improve, and the separating effect of each component also can significantly improve, and the success rate of separation also can significantly improve.
2, visual cylinder lower end also is provided with and vacuumizes interface, resin can be drained reality, has avoided glass can not bear too large pressure defective.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Sequence number among the figure: 1, visual cylinder, 2, minim pipette, 3, vacuumize interface, 4, a layer sieve plate, 5, vacuum-pumping tube.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
According to shown in Figure 1, a kind of chromatographic column of the utility model, comprise the minim pipette 2 that visual cylinder 1, visual cylinder 1 lower end arrange, described visual cylinder 1 lower end also is provided with and vacuumizes interface 3, the described interface 3 that vacuumizes is arranged on the vacuum-pumping tube 5, described minim pipette 2 is arranged in the vacuum-pumping tube 5, is provided with a layer sieve plate 4 in the described visual cylinder 1.
Embodiment is just for the ease of understanding the technical solution of the utility model; do not consist of the restriction to the utility model protection domain; every interior any simple modification, equivalent variations and modification of perhaps according to technical spirit of the present utility model above scheme being done that does not break away from technical solutions of the utility model all still belongs within the utility model protection domain.
