Graphite ferrules can withstand temperatures as high as 450 °C. Their inherent softness makes them ideal for metal columns and allows for additional installation tolerances.

• General purpose for capillary columns
• Suitable for FID, NPD, and ECD
• Recommended for high temperature and cool on-column applications
• Material is free of sulfur and other contaminants
• Can be reused or removed easily
• Proper installation requires a finger-tight turn on the nut, then an additional 1/4 turn with a wrench
• Not for use with MS or oxygen sensitive detectors

Graphite ferrules can withstand temperatures as high as 450 °C making them a top choice for high temperature applications. Their inherent softness and thermal expansion properties help to prevent column damage due to overtightening while maintaining a leak-free seal throughout temperature cycling. Agilent offers a comprehensive selection of 100% graphite ferrules made for use with a variety of GC columns. These ferrules are recommended for making leak-free connections between the GC column and injector port in high temperature applications.
