Agilent liner,direct,1.5mm ID, non-deactivated 18740-80200

The Agilent 18740-80200 is a straight, direct inlet liner with a 1.5 mm inner diameter and a non-deactivated interior that is intended for gas chromatography direct injections. Agilent lists this part specifically for gas samples, headspace, and purge & trap applications; it installs in the GC inlet to accept direct gas/sample introduction and interface with the analytical column. The liner’s 78.5 mm length and 140 µL internal volume make it suitable for low-volume gas/headspace transfers where direct injection is required.

Key Features:

• Component type: Inlet liner (direct)
• Inner Diameter (ID): 1.5 mm
• Length: 78.5 mm
• Internal volume: 140 µL
• Deactivation: None (non‑deactivated)
• Liner geometry: Straight

Advantages:

• Designed and specified by Agilent for gas samples, headspace, and purge & trap—ensures compatibility with those sample introduction modes.
• Direct‑connect, straight geometry is intended to aid complete transfer to the column and reduce inlet discrimination, supporting improved analyte recovery and sensitivity.
• Non‑deactivated construction with no glass wool makes it appropriate for relatively clean or gaseous samples where minimizing sample/liner interactions is important.
