AI Technical Summary
In existing mass spectrometry tests, root and stem plant samples tend to adhere to the cup wall during the crushing process, resulting in uneven crushing and large particle residue, which affects the detection results. In addition, traditional homogenizers require frequent shutdowns for manual cleaning, which is inefficient.
The sample pretreatment device, based on intelligent sensors, includes an anti-wall-attachment mechanism and an auxiliary mechanism. It automatically cleans up the adhered samples by utilizing the elastic deformation and inertia of the spring sheet and rubber sheet, and simultaneously achieves crushing and cleaning through motor and mechanical linkage.
This improved the uniformity and efficiency of sample fragmentation, avoided frequent downtime due to manual cleaning, reduced energy consumption and operating costs, and ensured the accuracy of mass spectrometer detection.
