Agilent Liner, UI 2mm dimpled splitless 5190-2297

The Agilent 5190-2297 is an Ultra Inert (UI) dimpled inlet liner for Agilent gas chromatographs, specified for splitless injections. It is a 2 mm inner diameter, single-taper glass liner (no glass wool) with a 200 µL internal volume and 78.5 mm length, intended for cold splitless/multimode inlet use and for analyses of active analytes and heavy matrix samples. The dimpled geometry increases inert surface area to spread sample deposits while the UI deactivation minimizes adsorption and sample interaction, supporting improved analyte recovery and longer usable life.

Key Features:

• Inner Diameter (ID): 2 mm
• Length: 78.5 mm
• Internal Volume: 200 µL
• Liner Geometry: Single taper, dimpled
• Deactivation: Ultra Inert (UI)
• Injection Type: Splitless
• Outer Diameter (OD): 6.45 mm

Advantages:

• Ultra Inert deactivation reduces adsorption and helps preserve active or labile analytes during splitless injections.
• Dimpled geometry increases inert surface area to spread sample deposits, improving performance with heavy matrix samples and extending liner life.
• Small 2 mm ID and 200 µL volume are optimized for cold splitless/multimode inlet and solvent‑vent workflows where small-volume handling is needed.
• Manufactured to Agilent dimensional tolerances (ground/polished OD) for consistent fit and reliable splitless inlet performance.
