Claim:
1. A particle test control method of particle analyzer, said method comprising: controlling a sample acquisition system to acquire a sample in a test location; injecting the acquired sample into a reaction cell to obtain a diluted sample; controlling a liquid addition system to acquire the diluted sample from a reaction cell and inject the acquired diluted sample into a counting cell, and keeping a liquid discharge valve of the reaction cell in a close status to maintain a residual diluted sample in the reaction cell; counting the sample in the counting cell by impedance method, and monitoring whether a pore blocking event occurs during counting; suspending counting and performing an unblocking operation if a pore blocking event occurs, wherein the unblocking operation comprises setting an anode electrode and a cathode electrode separately in the reaction cell and the counting cell, and supplying an electric current between the anode electrode and the cathode electrode to burn foreign matter blocking a pore; and controlling the liquid addition system to acquire the diluted sample again from the reaction cell and inject the acquired diluted sample into the counting cell after the unblocking operation, and re-counting the sample in the counting cell by impedance method.
