Sample processing method for automatic sample processing system

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.
