    Abstract: A fragmenting reaction of peptide is achieved while maintaining the isolated state of peptide. Isolated peptide fractions isolated by electrophoresis are prepared in flow paths. Subsequently, prepared peptide fractions are dried by each of the flow paths. Then, dried peptide fractions are in contact with protease. Then, independent liquid membranes of a solvent are formed over the surfaces of peptide fractions, which have been in contact with protease, disposed on the flow paths, respectively.

The analytical result is stored in a memory (369) while associated with position information in a driver control unit (367) and information on laser beam irradiation condition in a laser control unit (373), and the analytical result is imaged by an imaging unit (375). The imaged analytical result is displayed on a display (377).

  • Patent number: 7274016
    Abstract: A liquid sample (104) introduced in a main flow passage (101) is held in a dam portion (105), and a trigger liquid (106) is filled in a trigger flow passage (102). In this state, the trigger liquid (106) is further introduced at desired timing into the trigger flow passage (102) so that the front end portion of the level of the trigger liquid (106) is advanced and the front end portion is brought to be into contact with the dam portion (105). This causes the liquid sample (104) to move to the right (downstream side) in the figure, resulting in the liquid sample (104) flowing out to the downstream side of the main flow passage (101). This means that the trigger liquid (106) provides priming to realize a liquid switch.
