样品入口阀包括在一个罐形壳体相对于所述定子的定子（12）（44）和可调节的一个在两个切换位置（12）的转子（14），它在弹簧压力，并在60通过密封表面（34）邻接所述定子（12） °彼此错开的孔（18,46,48,50,54,56），并且包含60°延伸的连接通道（36,38）的角度。 的计量节流孔（18,40）延伸（12）和所述转子（14），并通过60°相对于通过所述定子的连接通道（38）的偏移。 在第一开关位置时，所述计量孔（18,40），以一个计量回路（22）和这对一个出口（60）连接。 用注射针（42），所述样品中，然后气泡放置。 取出转子的注射针（42）后（14）被引入到其中，计量回路（22）是一方面所述第二开关位置，在连接到输送流体源和一个分离柱另一方面。

A sample inlet valve comprises a stator (12) in a pot-shaped housing (44) and one in two switching positions relative to the stator (12) adjustable rotor (14) which abuts the stator (12) via a sealing surface (34) under spring pressure and at 60 ° staggered holes (18,46,48,50,54,56) and contains an angle of 60 ° extending connecting channels (36,38). A metering orifice (18,40) extends through the stator (12) and the rotor (14) and is offset by 60 ° with respect to a connecting channel (38). In the first switching position, the metering orifice (18,40) is connected to a metering loop (22) and this to an outlet (60). With an injection needle (42), the sample, and then an air bubble is placed. After withdrawing the injection needle (42) of the rotor (14) is introduced into the second switching position in which the metering loop (22) is on the one hand connected to a transport fluid source and secondly to a separation column.
