    • A ferrule arrangement for use in sealing connections to gas chromatography columns includes a generally tubular metal ferrule with an axial bore to receive a fracturable column with a protective coating. The ferrule has a forward part that tapers to a tip region of the ferrule. A generally tubular former has a socket portion to receive the ferrule and further has an internal conical surface that, after such receipt, engages the forward part of the ferrule. A portion is provided on either or both of said ferrule and the former by which the ferrule and former may be directly or indirectly relatively moved together by application of finger force. The taper and the internal conical surface exhibit relative taper angles and the tip region of the ferrule is sufficiently radially thin whereby the application of finger force (i) is adequate to move the ferrule axially into the former to cause the conical surface to engage the tip region of the ferrule and to deform the tip region into sealing engagement with the protective coating of the column, but (ii) does not break the column.
    • 用于与气相色谱柱密封连接的套圈装置包括具有轴向孔的大体上管状的金属套圈,以接收具有保护涂层的可分离柱。 套管具有朝向套圈的尖端区域逐渐变细的前部。 通常管状的成形器具有容纳套圈的插座部分,并且还具有内圆锥形表面,该锥形表面在接收之后接合套圈的前部。 一个部分设置在所述套圈和前者中的一个或两个上,通过该部分可以通过手指力直接或间接地相对地移动套圈和前者。 锥形和内锥形表面呈现相对的锥角,并且套圈的尖端区域充分地径向变薄,由此,手指力(i)的施加足以将套圈轴向移动到前者中,以使锥形表面接合尖端 并且使尖端区域变形成与柱的保护涂层密封接合,但(ii)不会破坏柱。
