Problems solved by technology
Due to the large amount of toxic organic solvents such as methanol and chloroform used in the chromatography process, a large amount of solvents volatilize into the environment, causing great harm to the health of operators and causing great pollution to the environment; secondly, due to the serious volatilization of solvents, open chromatography The system makes it difficult to reuse the eluent, resulting in serious waste and environmental pollution; thirdly, the traditional chromatography process requires manual addition of mobile phase, collection of fractions, rotary evaporation to recover products and eluents, and the operation is complicated

Embodiment Construction
[0019] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.
[0020] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

The invention relates to a chromatographic device which comprises a chromatographic column, a distilling apparatus, a condensing unit, a receiving container, a supply container, a first vacuumizing device and a negative pressure device, wherein the lower end of the chromatographic column is communicated or sealed with the distilling apparatus in an operable way, the condensing unit is communicated with the distilling apparatus and the receiving container to form a communication area, the first vacuumizing device is used for carrying out exhausting on the communication area to form negative pressure, the supply container is communicated or sealed with the receiving container in an operable way, the supply container is positioned above the chromatographic column and is communicated or sealed with the upper end of the chromatographic column in an operable way, and the supply container is respectively communicated or sealed with an atmosphere device and a negative pressure device in an operable way. For the chromatographic device, chromatography, recycling and circulating use of a solvent in a sealed system are realized, application is facilitated, volatilization of poisonous organic solvent in environment is reduced, and consumption of solvent is reduced; by adopting the supply container, negative pressure is sufficiently utilized, and the chromatography process is accelerated, so that the solvent is supplied from top to bottom in the chromatographic process.
Description
technical field [0001] The invention relates to a reaction device in the field of chemistry, in particular to a chromatographic device. Background technique [0002] At present, most of the chromatography systems used in laboratories or industrial production are open chromatography systems, that is, the chromatography columns are unclosed or semi-closed. Due to the large amount of toxic organic solvents such as methanol and chloroform used in the chromatography process, a large amount of solvents volatilize into the environment, causing great harm to the health of operators and causing great pollution to the environment; secondly, due to the serious volatilization of solvents, open chromatography The system makes it difficult to reuse the eluent, resulting in serious waste and environmental pollution; thirdly, the traditional chromatography process requires manual addition of mobile phase, collection of fractions, rotary evaporation to recover the product and eluent, and the...
