Agilent Liner,UI,splitless,dbl-taper,no wool 5190-3983

The Agilent 5190-3983 is an Ultra Inert (UI) gas chromatograph inlet liner engineered for splitless injections. It is a double‑taper, wool‑free glass liner designed to provide a low‑activity flow path for trace and active analytes, reducing adsorption and improving transfer of sample vapor to the column. Typical uses include trace‑level analyses and work with labile or active compounds on Agilent GC systems.

Key Features:

• Part number: 5190-3983
• Deactivation: Ultra Inert (UI)
• Injection type: Splitless
• Liner geometry: Double taper (dbl-taper)
• Inner diameter (ID): 4.00 mm
• Length: 78.5 mm
• Glass wool: None (no wool); Volume: 800 µL; Outer diameter: 6.47 mm

Advantages:

• Ultra Inert deactivation minimizes active sites and reduces analyte adsorption, improving recovery and sensitivity for trace or active compounds.
• Double‑taper, splitless design directs vapor toward the column and limits analyte contact with metal inlet surfaces, reducing decomposition and discrimination.
• Wool‑free construction avoids trapping or retention of labile analytes, making the liner suitable for fragile or easily adsorbed compounds.
