Graphite Ferrules for GC
Graphite ferrules offer exceptional sealing performance for most standard GC applications. The soft, malleable material can uniquely conform to nearly any space, reducing dead volume. This provides a leak-tight seal without risk of compromising the analytical column. Graphite capillary ferrules offer limited thermal expansion or contraction, meaning that column connections do not require regular maintenance to retain an efficient seal. Compared to polymeric materials, high-purity graphite ferrules are capable of withstanding inlet/oven temperatures up to 450 °C without loss in performance.
Agilent graphite ferrules are available in three standard sizes based on the capillary columns outer diameter (od). Larger 1/8 inch and 1/16 inch reducing ferrules are available for packed columns. For assistance selecting the correct ferrule for your application, try the Agilent GC Ferrule Selector Tool.

Features
- Graphite ferrules are recommended high-temperature applications exceeding 350 °C.
- With proper installation, graphite ferrules can be reused depending on the application.
- Graphite ferrules will not bond or stick-to the silica capillary column or metal inlet interface, allowing for easy removal.
- For convenience and cleanliness, Agilent Graphite ferrules are packaged in a rotating dial-pack.
- Graphite ferrules are not recommended for use with oxygen-sensitive columns or detectors such as MSD or ECD.
