technical field [0001] The invention relates to a sample mixing device and a using method, in particular to a high-efficiency sample oscillating and mixing device used in chemical analysis and a using method. Background technique [0002] At present, in chemical analysis, the detection of one item requires multiple reagents and multi-sample processing, and it is also necessary to mix the sample solutions to ensure the uniformity of the reagent samples. General mixing techniques include stirring, bubbling, ultrasonic, vortex, and vibration. These methods have many disadvantages: the automation of the vortex mixing method is low, and the samples need to be mixed manually one by one.

Problems solved by technology

These methods have many disadvantages: the automation of the vortex mixing method is low, and the samples need to be mixed one by one manually

The bubbling and magnetic mixing methods use a magnetic stirrer and a bubbling needle to mix the samples one by one, which takes a long time; and each time a sample is mixed, the stirrer and the bubbling needle must be cleaned, which consumes A large number of cleaning solvents; it is easy to bring the risk of sample loss and cross-contamination; the performance requirements for the corrosion resistance and organic solvent resistance of the bubbling needle are high, and the gas used for bubbling generally needs to use high-purity inert gas, which increases the cost of the experiment ; High cost of multi-site magnetic stirrer

Ultrasonic mixing method, complex structure, expensive, and ultrasonic mixing must have liquid to transmit ultrasonic waves, which limits the combination of this technology on other instruments

The polarization motor oscillation mixing method is a transmission oscillation method, not direct oscillation. The sample can only be mixed by circular motion in the horizontal direction of the sample, and the mixing efficiency is poor.
