    • A system for dispensing a sample (5) into a buffer liquid comprises a pressure chamber (1) having pressure supply means for generating an overpressure within the pressure chamber. An inlet capillary (2) is provided for supplying a buffer liquid (9) to an outlet end (6) arranged in the pressure chamber. Also, an outlet capillary (3) is provided for discharging buffer liquid and/or sample from the pressure chamber. The outlet capillary (3) has an inlet end (7) arranged in the pressure chamber (1) facing the outlet end (6) of the inlet capillary (2) to form a capillary gap (8). A dispenser (4) having a dispensing end (10) is arranged in the pressure chamber (1) at the capillary gap (8) to allow the sample (5) at the dispensing end (10) to be dispensed from the dispensing end (10) into the buffer liquid entering the inlet end (7) of the outlet capillary (3). The pressure chamber (1) comprises a pressure-tight sample port (13) adapted to allow the dispenser (4) with the dispensing end (10) to be moved into and out of the pressure chamber (1), wherein the pressure chamber (1) comprises a pressure-tight sample port adapted to allow the dispenser (4) with the dispensing end (10) to be moved into and out of the pressure chamber ( 1 ).
    • 用于将样品(5)分配到缓冲液体中的系统包括具有用于在压力室内产生超压的压力供应装置的压力室(1)。 提供入口毛细管(2),用于将缓冲液(9)供应到布置在压力室中的出口端(6)。 而且,出口毛细管(3)用于从压力室排放缓冲液体和/或样品。 出口毛细管(3)具有布置在压力室(1)中的入口毛细管(2)的出口端(6)的入口端(7),以形成毛细管间隙(8)。 具有分配端(10)的分配器(4)在毛细管间隙(8)处设置在压力室(1)中,以允许在分配端(10)处的样品(5)从分配端 10)进入进入出口毛细管(3)的入口端(7)的缓冲液中。 压力室(1)包括适于允许具有分配端(10)的分配器(4)进入和离开压力室(1)的压力密封样品端口(13),其中压力室 1)包括适于允许具有分配端(10)的分配器(4)进入和离开压力室(1)的耐压样品端口。
