Summary:PROBLEM TO BE SOLVED: To control the ion permeability (sensitivity).SOLUTION: A mass spectroscope includes an ionization unit 2 for ionizing a sample, an ion guide 3 having at least four rod-like electrodes and transporting ions, a mass spectrometry unit 4 performing mass separation and having at least four rod-like electrodes, a detection unit 5 that detects ions that have passed through the mass spectrometry unit 4, and a control unit 8 controlling a voltage applied to the ion guide 3, and the control unit 8 varies the passing energy of the ions passing through the ion guide 3 according to the characteristics of the target ions.SELECTED DRAWING: Figure 3 【課題】イオン透過率（感度）をコントロールする。【解決手段】質量分析装置は、試料をイオン化するイオン化部２と、少なくとも４本の棒状電極を有し、イオンを輸送するイオンガイド３と、質量分離を行う、少なくとも４本の棒状電極を有する質量分析部４と、質量分析部４を通過したイオンを検出する、検出部５と、イオンガイド３に印加する電圧を制御する制御部８と、を有し、制御部８は、イオンガイド３を通過するイオンの通過エネルギーを、ターゲットとするイオンの特性に応じて変動させる。【選択図】図３
