Abstract

The invention discloses a sample application system and method. The system comprises at least one sample storage unit, a sample application unit, a positioning unit and a drying unit, wherein a quantitative outputting device is arranged at an outlet of the sample storage unit; the sample application unit is provided with at least one sample application needle; the sample application needle can be connected with the quantitative outputting device in the manner of sliding up and down; the positioning unit is located under the sample application unit; the positioning unit is provided with a fixing table and at least one sample application ruler; at least one group of positioning holes are formed in the sample application ruler; the drying unit comprises a hot air pipe, an air feeding pipe and a hot air device; the hot air pipe is moveably arranged above the sample application ruler; at least one outlet is formed in the position, corresponding to the positioning holes of the positioning unit, on the hot air pipe. Thus, the system can be used for performing synchronous sample application on a plurality of samples according to the experiment requirement, can realize the quick, efficient and controllable completion of the sample application process by controlling and regulating the sample application volume and the size of sample application point, can accumulate the experiment parameters and can guarantee the efficiency of the experiment operation.

Description

technical field [0001] The invention belongs to the field of chromatographic analysis, in particular, the invention relates to a sample pointing system and method. Background technique [0002] Plane chromatography mainly includes thin-layer chromatography and paper chromatography. The former is more widely used and is a common method in the field of pharmaceutical or chemical synthesis. It is very fast, convenient, and low-cost for real-time monitoring of reaction progress and qualitative observation of reaction products. low merit. However, the current conventional sample spotting methods are divided into spot spotting and strip spotting, both of which use manual spotting, which is difficult to achieve satisfactory results in sample separation, and only one injector can be placed for each spotting. low efficiency. [0003] Therefore, the current spotting technology still needs to be further improved. Contents of the invention [0004] The present invention aims at sol...
