Zusammenfassung: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. 일 개시에 의하여, 질량지수 k의 질량 스펙트럼에 해당하는 이온신호들로 구성된 이온신호블록 xk 을 도출하는 단계, 기 정해진 2차 곡선 피팅 결과에 따른 질량 지수에 대응하는 신호 블록의 유형 테이블을 이용하여 이온신호블록 JPEG112019136038252-pat00062.jpg611의 유형을 판별하는 단계, 이온신호블록 JPEG112019136038252-pat00063.jpg611의 유형에 해당하는 특징에 기초하여 질량지수 k에 해당하는 이온신호들을 선택하여 2차 피팅 곡선을 생성하는 단계, 2차 피팅 곡선의 최대값에 해당하는 질량지수위치로부터 피크위치오차를 결정하는 단계를 포함할 수 있다.
