    • In this chromatograph for pressure chromatography, a plunger having a plunger stem is arranged so that it can move within the separation column (3). On the front face of the plunger there is a collecting space (7) for liquid, which is covered by a frit (6) and which has a connecting line (8) to the face of the plunger opposed to the front face. In order to prevent abrasive and chemical attack by the column packing on the plunger, its seal and the cylinder wall of the separation column, the plunger should comprise a lower part (2) having a device (4) to accommodate the plunger stem (5), and an upper part (1), the two parts being arranged so that they can move in relation to one another. The upper part (1) has a centering peg (9) which projects into the lower part (2). A spring (12) on which the upper part (1) is supported, is located concentrically in relation to the peg (9). The upper part (1) has recesses on its circumference to accommodate at least two seals (19 and 21) and a ring channel (16) which is formed by a retaining ring (13) for one seal (19) and is connected to the collecting space (7). The other seal (21) is held in its recess by a ring (23) which is located concentrically around the spring and is supported by the lower part.
    • 在这种压力色谱色谱仪中,具有柱塞杆的柱塞被布置成使其能够在分离柱(3)内移动。 在柱塞的前表面上有用于液体的收集空间(7),其被玻璃料(6)覆盖,并且具有与前表面相对的柱塞的表面的连接线(8)。 为了防止柱塞上的柱填料,其密封件和分离柱的气缸壁的研磨和化学侵蚀,柱塞应包括具有装置(4)的下部(2),以容纳柱塞杆(5) )和上部(1),两个部分被布置成使得它们可以相对于彼此移动。 上部(1)具有突出到下部(2)中的定心栓(9)。 支撑上部(1)的弹簧(12)相对于钉(9)同心地定位。 上部(1)在其圆周上具有凹部以容纳至少两个密封件(19和21)和环形通道(16),该通道由用于一个密封件(19)的保持环(13)形成,并且连接到 收集空间(7)。 另一个密封件(21)通过环(23)保持在其凹部中,环(23)同心地位于弹簧周围并由下部支撑。
