  • FERRULE FOR MAKING FINGERTIGHT COLUMN CONNECTIONS IN GAS CHROMATOGRAPHY
    Publication number: 20120169040
    Abstract: 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.
