Agilent Ferrule, 1.0mm Graphite 0.53 col 10/PK 5080-8773

Agilent part 5080-8773 is a pack of ten 100% graphite ferrules with a 1.0 mm ferrule ID specifically made for 0.53 mm capillary GC columns. These ferrules form the mechanical, leak‑free seal between the capillary column and the GC inlet or detector and are recommended by the manufacturer for high‑temperature and cool‑on‑column applications. Agilent describes them as suitable for common detectors such as FID, NPD, and ECD but not for mass spectrometry or oxygen‑sensitive detectors. The graphite construction is described as sulfur‑free and capable of withstanding temperatures up to 450°C.

Key Features:

• Manufacturer part number: 5080-8773 (Agilent)
• Ferrule material: 100% graphite
• Ferrule inner diameter (ID): 1.0 mm
• Compatible column ID: 0.53 mm capillary columns
• Pack quantity: 10 per pack
• Maximum temperature rating: 450°C
• Intended technique: Gas Chromatography (GC)

Advantages:

• High temperature tolerance (up to 450°C) for demanding GC runs and high‑temperature columns
• Soft graphite construction reduces risk of column damage from overtightening while preserving a leak‑free seal during thermal cycling
• Material is free of sulfur and other contaminants, lowering contamination risk
• Reusable and easy to remove; manufacturer recommends finger‑tight installation plus an additional 1/4 turn with a wrench for proper sealing
