An automatic rotary cleaning device for sampling bottles suitable for gas-liquid chromatography-mass spectrometry

Abstract

The invention relates to an automatic rotating and washing device for a gas-liquid chromatography-mass spectrography method. The automatic rotating and washing device comprises a sample introduction bottle clamping mechanism, a drive mechanism, a rotating mechanism, a scrubbing mechanism, a spray-washing mechanism and a waste liquid tank. The sample introduction bottle clamping mechanism is used for fixing a sample introduction bottle to a drive device. The drive mechanism is used for transporting the sample introduction bottle to the rotating mechanism and located above the waste liquid tank. The rotating mechanism is used for driving the sample introduction bottle clamping mechanism to rotate, so that a bottle opening of the sample introduction bottle fixed to the clamping mechanism faces downwards to be aligned with the waste liquid tank. The spray-washing mechanism is used for spray-washing the interior of the sample introduction bottle. Compared with the prior art, the sample introduction bottle with the volume smaller than 1.5 ml is rapidly and accurately washed automatically, no manual operation is needed, and the time spent on the later completion stage washing process of the gas-liquid chromatography-mass spectrography method is shortened.

Description

technical field [0001] The invention relates to a cleaning device, in particular to an automatic rotary cleaning device for sampling bottles suitable for gas-liquid chromatography-mass spectrometry. Background technique [0002] Gas-liquid chromatography-mass spectrometry has made great progress in application since its inception. There are more than 200,000 organic compounds in the standard mass spectrometer libraries of instrument manufacturers such as Agilent and Shimadzu. Among them, the standard detection chart of pesticide residues is included. Therefore, gas-liquid chromatography-mass spectrometry is widely used in the field of food and chemical testing. Products with large quantities and the same type of testing items can be tested by the same detection method in gas-liquid chromatography-mass spectrometry. Among them, the 1.5ml small-capacity sampling bottle in the sampling device is an important tool in the entire detection process, and cleaning the used 1.5ml sma...

AI Technical Summary

Problems solved by technology

It has the following problems: ① When cleaning, the staff needs to shake out the solution in the 1.5ml small volumetric bottle by hand. If a large number of samples are operated, repetitive work takes up a lot of working time, resulting in low efficiency of the entire cleaning process; ② Due to the small volume of the 1.5ml small-capacity sampling bottle, it is easy to pollute the outer surface of the small-capacity sampling bottle during the process of throwing out the solution, causing secondary pollution and increasing the cleaning workload

③During the transfer process, due to the manual operation, human organs such as fingers will come into contact with the sample solution, or volatile organic gases enter the human body through respiratory organs, and most of the solvents in the sample solution are toxic and harmful substances such as toluene and n-hexane Organic solvents cause great harm to human health and do not meet the requirements of people-oriented work
