Problems solved by technology
[0003] At present, most of the injectors need to be manually operated, and the amount of samples stored in the injector is small, which seriously affects the collection efficiency of the injector. At the same time, the sampling needle of the injector cannot be cleaned in time, making the injection There are many inconveniences in the use of the injector; therefore, it is necessary to design a sample injector with automatic positioning, collection and cleaning functions and its use method

The invention discloses a sample injector with automatic positioning, collecting and cleaning functions and a using method thereof. The sample injector comprises a base, an X-axis assembly, a Y-axis assembly, a Z-axis assembly, a cleaning assembly, a sample assembly and a standard product assembly. The upper surface of the base is provided with a shell, the X-axis assembly is installed in the shell, the Y-axis assembly is arranged on the upper surface of the X-axis assembly, the Z-axis assembly is mounted on the upper surface of the Y-axis assembly, and a sample assembly, a standard product assembly and a cleaning assembly are arranged on the upper surface of the base. The sampling needle is automatically positioned by adopting a cross coordinate positioning mode of the X-axis assembly and the Y-axis assembly, a sample and a standard substance can be collected under the matching action of the Z-axis assembly, the sampling needle after sampling can be automatically cleaned in real time, manual intervention is not needed in the whole process, the sample collecting efficiency is higher, the performance is more stable, and the device is suitable for being widely popularized and used.
Description
technical field [0001] The invention relates to the technical field of sample injectors, in particular to a sample injector with automatic positioning, collection and cleaning functions and a use method thereof. Background technique [0002] In chromatographic experimental analysis, the device that can quantitatively send samples into the chromatographic column is called a sampler; the sampler is divided into two types: manual sampler and automatic sampler, and the automatic sampler is a kind of intelligent It is a modernized and automated sampling instrument, only need to set the sampling parameters, put in the sample to be tested, and then the automatic sampling process can be completed. [0003] At present, most of the injectors need to be manually operated, and the amount of samples stored in the injector is small, which seriously affects the collection efficiency of the injector. At the same time, the sampling needle of the injector cannot be cleaned in time, making the...
