Sample processing method for automatic sample processing system

Abstract

The invention discloses a sample processing method for an automatic sample processing system. The automatic sample processing system comprises a workbench, wherein a sample preprocessing mechanism, a sample centrifuging mechanism, a sample temperature controlling mechanism, a manipulator system, a testing mechanism and a test tube stand are arranged on the platform of the workbench; the sample preprocessing mechanism comprises a support and a plurality of jacking test tube brackets; a sample smashing mechanism used for smashing solid samples and a plurality of servo-type burettes are arranged on the support; the sample smashing mechanism comprises a smashing motor and a smashing mechanism; the smashing motor is fixed on a fixing frame; the smashing mechanism is arranged on the output shaft of the smashing motor. The sample processing method comprises the following steps: sample smashing, reagent adding, liquid extracting, centrifuging, temperature controlling, eluting and detecting. According to the invention, the sample processing method has the following advantages: the samples can be smashed automatically, a reagent can be added automatically, and liquid can be extracted automatically; the accuracy of adding and extracting the liquid is high.

Description

technical field [0001] The invention relates to a sample processing method of an automatic sample processing system. Background technique [0002] In the transportation and storage of grain, food, etc., it is often necessary to carry out random sampling and testing in order to accurately grasp the quality of grain, find grain quality problems in time, and take corresponding solutions. At present, it is often necessary to carry out genetic analysis on some grains or foods to confirm whether they are genetically modified grains or foods. In the process of this genetic analysis, the sampling requirements for grain or food are relatively strict, and the sampled samples must be pulverized (solid samples), added reagents, centrifuged, heated or cooled before they can be tested and analyzed. [0003] The traditional method is manual processing. The staff manually completes the sample crushing (solid sample), adding reagents, centrifuging, heating or cooling, etc., which not only t...

Problems solved by technology

[0005] However, there is no device for crushing samples and adding reagents in this sampler. These tasks need to be done manually, which has problems such as time-consuming and labor-intensive, low packing efficiency, and high labor intensity.
