To ensure that the liquid drop is slowly delivered under quasi-equilibrium condition in drop analysis, a microflow feeding pump actuated by a single stepping motor and controlled by the computer software is improved. The function of switching and injecting can be effectively realized and the cost is reduced. It can exclude the influence of bubbles. The photo signal of an embedded photoelectric sensor is used to control the movement of the syringe so as to avoid the step-missing condition. The computer software is used to solve the possible problems caused by the accidental mechanical block or sudden power cut. A kind of one-time syringe is designed for some liquids difficult to clean. Average method in the dynamic drop monitoring process is used to smooth the signals with high-frequency noise. A representation of the liquid drop fingerprint based on equivalent drop volume percentage is developed by normalizing the capacitive signal to solve the problem of magnification variation. |
