Patent ID: 8062516

Claim:
A connector for connecting a gas chromatography capillary column to chromatography equipment, the equipment having a connection for releasably connecting to capillary columns, the connector having a longitudinal axis along which the capillary column extends during use, the connector comprising: a securing body having an upstream and downstream end with a ferrule recess in the upstream end configured to receive an upstream ferrule, the securing body having an annular recess extending around an exterior circumference of the downstream end; a securing nut holding the upstream ferrule in the securing body; and a main body having an upstream and downstream end with a recess in the upstream end of the main body being sized to slidably and rotatably receive the downstream end of the securing body and with the upstream end of the main body configured to releasably connect with the releasable connection on the equipment, the downstream end of the main body having a ferrule recess into which a downstream ferrule can be placed during use, the main body having a part extending into the annular recess to limit motion of the securing body relative to the main body in at least one direction along the longitudinal axis, with the longitudinal axis extending through the securing nut, upstream ferrule, securing body and main body.
