UV-PD of some protonated peptides was investigated using a tandem TOF spectrometer equipped with a cell near its first time focal point where the laser was irradiated. When a high voltage was applied to the cell, each product ion peak split into in-cell, post-cell and consecutive components. Each time-resolved product ion peak depend on the position of their photodissociations. A method based on flight time calculation was developed to analyze these component and to identify the intermediate ion for each consecutive component.
