Abstract
A connector for fastening a gas chromatography capillary column to chromatography equipment includes a securing nut and ferrule on a first portion of the connector for releasably holding the capillary column in a position relative to a second portion of the connector. The first portion rotates relative to the first portion and translates a limited amount relative to the first portion. A pin on the first portion extending into an annular groove around a circumference of the first portion may allow this rotation and limited translation. The second portion has a threaded end adapted to screw into the chromatography equipment with the first portion remaining relatively rotation free as the second portion is screwed into place.
