Agilent Liner,splitless,dbl-tpr,no glswl,deacted 5181-3315

The Agilent 5181-3315 is a deactivated, double-taper inlet liner designed for splitless injections on Agilent gas chromatographs. It provides an inert transfer path from the inlet to the column and is intended for use in splitless sample introduction where minimizing adsorption and thermal decomposition is important. The liner has no glass wool and is sized to accommodate typical splitless vapor volumes.

Key Features:

• Injection type: Splitless
• Liner geometry: Double taper
• Inner diameter (ID): 4 mm
• Length: 78.5 mm
• Deactivation: Standard deactivation (deactivated surface)
• Volume: Approximately 800 µL; Glass wool: None

Advantages:

• Deactivated internal surface reduces analyte adsorption and helps minimize thermal decomposition during splitless injections.
• Double-taper geometry and ~800 µL vapor volume are suitable for typical splitless methods, supporting efficient vapor transfer to the column.
• Absence of glass wool lowers the risk of irreversible adsorption for active analytes (e.g., phenols, amines), making it preferable for sensitive compounds.
• Designed for direct use with Agilent GC inlets for straightforward replacement and inlet compatibility.
