The Agilent Collared Column Nut, Self-Tightening MSD (part number G3440-81013) is a stainless‑steel, spring‑driven capillary column nut designed for GC/MSD interfaces. It provides a finger‑tight, locking‑collar design that continuously presses on short graphite/polyimide ferrules to maintain a leak‑free seal and reduce the need for retightening. Agilent indicates the nut is especially suited for oxygen‑sensitive detectors (for example MSD and ECD) and for improving reproducible column installation.
Key Features:
- Manufacturer part number: G3440-81013.
- Material: stainless steel (self‑tightening GC column nut).
- Design features: spring‑driven piston and locking collar (self‑tightening, collared).
- Compatibility: intended for MSD/GC‑MS detector interfaces.
- Recommended ferrules: compatible with short 85:15 polyimide/graphite ferrules — part numbers 5181-3323, 5062-3514, 5062-3512 (for listed column IDs).
Advantages:
- Eliminates frequent retightening: spring action maintains seal over hundreds of injections, reducing maintenance.
- Finger‑tight, faster installations: winged/finger‑tight design speeds maintenance and reduces instrument downtime.
- Improves data quality for oxygen‑sensitive detectors: tight, low‑torque seal reduces leaks and background noise for MSD/ECD applications.
- Locking collar supports reproducible column depth and consistent installation results.
