摘要（英）：

The present invention provides a system and a method for reducing the space charge effect in a linear ion trap. The system includes a linear ion trap, a first AC power supply, a second AC power supply, and a RF power supply. The linear ion trap includes four identical electrode rods, where two poles of the first AC power supply are respectively connected to two of the electrode rods, and two poles of the second AC power supply are respectively connected to the other two electrode rods. Two poles of the RF power supply are respectively connected to the first AC power supply and the second AC power supply. The first AC power supply and the second AC power supply provide sinusoidal AC signals. The present invention reduces the resolution decrease caused by the space charge effect, thereby improving analytical performance in mass spectroscopy.
