an autosampler

Abstract

The invention belongs to the technical field of analysis and detection, and relates to an automatic sample injector, which includes a sample feeding part, a conveying part, a positioning detection part, a sample table with a plurality of sample reservoirs placed thereon, and a connection with the sample feeding part, the conveying part, and the positioning detection part The control part; the sample feeding part is fixed on the conveying part, and the conveying part is used to transport the sample feeding part to the designated position of the sample table; the positioning detection part arranged under the sample feeding part is used to detect whether there is a sample container in the designated position, If it exists, the control unit controls the sampling unit to inject samples, and if it does not exist, the control unit outputs a stop operation instruction. It can automatically judge whether the delivery position is accurate and whether there is a sample reservoir in each position of the sample table, so as to avoid the failure of sample injection, and can also continue to inject samples from any position without having to start all over again, saving time and cost. The control part can obtain the instrument signal, and operate when the instrument is turned into a ready state, which further improves the success rate of analysis.

Description

technical field [0001] The invention relates to an automatic sample injector and belongs to the technical field of analysis and detection. Background technique [0002] With the continuous development of technology, the automatic sampler has become the standard configuration of analytical and testing instruments because of its continuous automatic sample injection, unattended, and improved work efficiency. Common samplers mainly include disc type and three-axis gantry type. Although it can be applied to liquid sampling, it cannot realize gas sampling through the extension piece, and when the moving position deviates, the sampler cannot detect and stop the sampling in time, so it is necessary to design an application that can detect gas. Is the injector correct and the sample reservoir is present. Contents of the invention [0003] In view of the deficiencies in the prior art above, the purpose of the present invention is to provide an automatic sample injector, which can...

Although it can be applied to liquid sampling, it cannot realize gas sampling through the extension piece, and when the moving position deviates, the sampler cannot detect and stop the sampling in time, so it is necessary to design an application that can detect gas. Is the injector correct and the sample reservoir is present?
