Agilent, 5190-3165, Inlet liner, Ultra Inert, split, low pressure drop, glass wool, 5/pk

The Agilent Ultra Inert Split GC Inlet Liner is designed for split injections at high carrier-gas flow and high split ratios. This low-pressure-drop liner uses an Ultra Inert deactivated surface and a mid-positioned quartz glass-wool plug to support sample vaporization and capture nonvolatile residues. Its single-taper geometry helps reduce inlet turbulence and backpressure near the column entrance. The liner has a 4 mm internal diameter, 6.25 mm outer diameter and 78.5 mm length, with a nominal volume of 870 µL. Five liners are supplied in one package. For consistent chromatography, use clean handling tools, avoid touching the deactivated internal surface and select appropriate inlet seals during replacement. Inspect chromatograms for signs of active-site adsorption, peak tailing, contamination or discrimination, especially when challenging sample matrices are analyzed. Replace liners at a frequency supported by sample cleanliness and system performance. This product is for split injection, not a splitless-specific liner or a complete GC inlet module.
