Problems solved by technology
However, since the sample vials are all small-bore containers and are not easy to clean, they are mostly used for one-time use, which increases the cost of equipment consumables to a certain extent, and also causes a certain waste of resources.
[0004] HPLC, GC and other chromatographic analysis will consume a large number of sample bottles when processing samples in batches. The material of sample bottles is generally glass, which is a reusable consumable. However, due to the small diameter of sample bottles, there is currently no such sample bottle. For more mature cleaning methods, if the traditional "manual + test tube brush" cleaning mode is used, not only the workload is huge, but also it is not easy to clean, which will affect the secondary use effect
Therefore, in order to avoid cross-contamination between samples, many laboratories use disposable sample bottles, which increases the cost of equipment consumables and wastes resources.

An apparatus and method for cleaning chromatography sample vials. The apparatus comprises: a base (1); a support frame (20) that is vertically fixed on the base (1); a transverse column (21) that has one end thereof arranged on the support frame (20) via an adjustment knob (22) and has a rotary transmission apparatus (3) fixed on the other end; a rotating disk (4) that is connected at the lower extremity of the rotary transmission apparatus (3), can be driven by the rotary transmission apparatus (3) into rotation, and is provided at a lateral edge with multiple sample vial accommodating holes (40) used for accommodating and securing to-be-cleaned sample vials; a cleaning agent recovery tank (5) that is arranged below the rotating disk (4) and is provided with an injection pipe (7) at the sidewall, where the injection pipe (7) is connected to a water pump (8), and the water pump (8) is in communication with a cleaning agent container (90); and, at least one control apparatus that is used for controlling the turning on / off and rotational speed of the rotary transmission apparatus (3) and for controlling the turning on / off of the water pump (8). The apparatus allows for increased efficiency in cleaning small caliber sample vials.
Description
technical field [0001] The invention relates to cleaning equipment, in particular to a chromatographic analysis sample bottle cleaning device and cleaning method. Background technique [0002] High Performance Liquid Chromatography (HPLC) analysis and Gas Chromatography (GC) analysis, as two important branches of chromatography analysis, are widely used in environmental monitoring, pharmacy, medicine, thin film transistor-liquid crystal display (TFT-LCD) and other industries, for example, in the TFT-LCD industry, these two chromatographic analysis methods are often used when analyzing components such as liquid crystal, stripping liquid, and photoresist. [0003] The analytical devices used in the HPLC and GC analysis methods can be divided into a sampling system, a separation system and a detection system in structure. Among them, the sampling system will use an autosampler. The use of the autosampler brings great convenience to the batch processing of samples, greatly impr...
