Claims (1)
- 質量分析部として、イオンを生成するイオン源と、イオンを加速する為の加速部および、加速されたイオンの質量/電荷比を計測する飛行時間型質量分析部を備えた質量分析装置において、
前記イオンを加速する為の前記加速部の電極に高電圧を出力する高圧電源回路と、
該高圧電源回路に設置された温度センサーと、
前記高圧電源回路に設置された温度センサーの温度データに基づき、前記加速されたイオンを計測して得られた質量数に対する相対的な質量数のずれを算出して実際の観測値を補正するデータ処理部と、を備え、
前記データ処理部は、質量数の相対的なずれ量と、前記高圧電源回路の温度との関係を示す一次の比例関数の式を用いて、相対的な質量数のずれを算出することを特徴とする質量分析装置。
