PROBLEM TO BE SOLVED: To provide an improved microflow control system for reducing delay time in gradient high-speed liquid chromatography. SOLUTION: In this method, a device, which includes a mechanism for optionally diverting a part of mobile phase, flowing through a mobile phase transport pipe, into a liquid transport pipe containing stationary phase to separate sample components, is used. This device is equipped with the liquid transport pipe, containing stationary phase communicated with at least one mobile phase transport pipe which includes the mechanism for optionally diverting a part of mobile phase flowing through the mobile phase transport pipe, and the remainder of the mobile phase flows into the liquid transport pipe containing the stationary phase.

PROBLEM TO BE SOLVED: To provide a technique for multi-dimensional separation of samples, which is suitably applicable to biological molecular analysis although it is easy to manufacture and simple in structure. SOLUTION: The device for separation comprises a first substrate containing a first separated fluid transport mechanism for separating molecules in a sample according to a first characteristic and a second substrate including a second separated fluid transport mechanism for separating molecules in the sample according to a second characteristic. The first and second substrates are located in different planes, and the first and second separated fluid transport mechanisms are mutually connectable by being controlled.

Abstract:
Ein Fluidtrennsystem (10) zum Trennen von Verbindungen eines Probenfluids in einer mobilen Phase weist einen Detektor (50) zum Detektieren der getrennten Verbindungen durch Senden eines optischen Anregungssignals in das Probenfluid und zum Empfangen eines Antwortsignals als Reaktion auf das optische Anregungssignal auf. Der Detektor (50) weist eine Lichtquelle (100) zum Senden eines Ausgangslichtstrahls (230) als optisches Anregungssignal auf. Die Lichtquelle (100) weist eine Vielzahl von lichtemittierenden Elementen (200, 200A, 200Z), die jeweils zum Emittieren eines Lichtstrahls (210, 210A1, 210A2, 210Z1, 210Z2) mit jeweils einer bestimmten Wellenlänge dienen, und ein Beugungselement (220) auf. Die Vielzahl der lichtemittierenden Elemente (200, 200A, 200Z) sind so angeordnet, dass die emittierten Lichtstrahlen (210, 210A1, 210A2, 210Z1, 210Z2), die in Abhängigkeit von ihrer jeweiligen Wellenlänge unter einem bestimmten Winkel auf das Beugungselement (220) auftreffen, durch das Beugungselement (220) zum Ausgangslichtstrahl (230) gebeugt werden.
