Problems solved by technology

At present, most instruments adopt the superposition design method to design the three-dimensional motion sampling device. The main feature is that the motion mechanisms of each dimension are superimposed from the bottom layer upwards. If the protective device is added, the reliability of the sampling device will be reduced and the volume will increase, which is not conducive to the miniaturization of the analytical instrument and the improvement of the reliability of th...
