Regulating filling process for measuring cell of ion cyclotron resonance mass analyzer involves supplying fraction of samples to reference mass spectrometer operated in parallel and acquiring reference mass spectrum

摘要

Regulating a filling process for a measuring cell of an ion cyclotron resonance mass analyzer with mixtures of ions, generated from a flow of substances, involves providing an ion cyclotron resonance mass analyzer with a measuring cell and a reference mass analyzer; supplying a fraction of mixture of ions to the reference mass analyzer to acquire a reference mass spectrum; evaluating the reference mass spectrum to obtain parameters to regulate the filling process; and regulating the filling process of the measuring cell of the ion cyclotron resonance mass analyzer by using parameters. An independent claim is included for an ion cyclotron resonance mass spectrometer comprising an ion source, an ion beam splitter, an ion cyclotron resonance mass analyzer, a reference mass analyzer, an evaluation system, and control devices for filling of measuring cell of ion cyclotron resonance mass analyzer.
