초록

A septum for an injection port of a gas chromatograph includes interlocked syringe and duckbill seals. The syringe seal prevents fluid leakage during injection by syringe. The duckbill seal prevents fluid leakage after the syringe needle is withdrawn from the septum. A spring clip is used to urge the duckbill closed as the needle is withdrawn. An advantage of this two component septum is that the duckbill slit can be precisely formed in the duckbill seal before the seals are engaged.

청구항

A septum for permitting injection of a fluid by extension of a needle therethrough, said needle having an injection diameter, said septum comprising: aperture means for defining a complex aperture, said complex aperture including an annular aperture with a minimum diameter and a duckbill aperture with a duckbill perimeter, said aperture means including elastic material bounding said complex aperture, said minimum diameter being less than said injection diameter when no needle is penetrating therethrough, said minimum diameter being substantially equal to...
