AI Technical Summary
The problem of inaccurate sample detection in existing technologies is mainly due to the fact that the sample cannot be accurately placed when it is pushed into the detection position, resulting in low detection accuracy.
The sample analyzer is controlled by the first and second valves in the pressure balance module to control the pressure difference between the sample and the sheath fluid module, ensuring that the sample and sheath fluid are uniformly transferred to the flow chamber. The drive module is used to transfer the sample to the predetermined position, and the sheath fluid module forms a sheath flow to protect the sample.
It improved the accuracy of sample transmission, reduced the amount of samples discarded at the beginning and end, increased the sample participation rate, and saved costs.
