[Abstract]:A microfluid oil detection chip based on inductance principle is introduced. The effect of the rate of iron particles passing through the detection area of microfluid oil detection chip on the particle counting sensitivity is studied. The microfluidic oil detection chip was made and the detection system was built. The relationship between the different driving rates and the amplitude of the inductance pulse signal produced by the particle is studied experimentally. The results show that the amplitude of the inductance pulse signal decreases linearly with the increase of the rate for the same iron particle. The results provide a reference for improving the detection accuracy and sensitivity of microfluid oil detection chip.
