Agilent Column nut kit, MS Self Tightening TMO 8002-0010

The Agilent Column nut kit, MS Self Tightening TMO (part number 8002-0010) is a kit of self‑tightening GC column nuts designed to provide consistent, leak‑free connections for GC/MS systems. The kit includes nuts for the SPL inlet and the MS transfer line plus graphite/polyimide ferrules sized for 250 µm columns, and is offered for Thermo Trace and Focus GC systems. The self‑tightening design uses a spring‑driven piston and a locking collar to maintain a stable seal and simplify column installation for oxygen‑sensitive detectors such as MS and ECD.

Key Features:

• Manufacturer part number: 8002-0010
• Includes nuts for SPL inlet and MS transfer line
• Includes 10 graphite/polyimide ferrules, 0.4 mm inner diameter (for 250 µm columns)
• Compatible with Thermo Trace and Focus GC systems
• Stainless steel nut body with spring‑driven piston sealing mechanism

Advantages:

• Maintains a leak‑free seal over many injections—spring‑driven piston continuously presses on the short ferrule to prevent leaks
• Finger‑tight, low‑torque design and locking collar enable easy, repeatable column installation without tools
• Well suited for oxygen‑sensitive detectors (MS, ECD) and helps reduce background noise
• Reduces maintenance time because fittings do not require frequent re‑tightening after thermal cycles
