| description | The present invention relates to a method for improving a mass spectrum resolution of a chromatography mass spectrometer, which is capable of effectively analyzing an organic compound injected into input gas. The method comprises the steps of: deriving an ion signal block (x_k) composed of ion signals corresponding to a mass spectrum of a mass index (k); determining the type of the ion signal block (x_EK) using a type table of a signal block corresponding to the mass index according to a predetermined quadratic curve fitting result; generating a quadratic fitting curve by selecting ion signals corresponding to the mass index (k) based on the characteristics corresponding to the type of the ion signal block (x_EK); and determining a peak position error from a mass index position corresponding to the maximum value of the quadratic fitting curve.
