Perkin Elmer, N6502032, 4 mm, Ultra Deactivated Single Low Pressure Drop Precision Liner with Wool

Inlet liners for split injection have mixing chambers with tortuous flow paths to allow full vaporization of the sample. Deactivating the surface of these liners prevents active compounds from degrading. Packing the liner with wool will trap non-volatile residue and prevent column contamination when analyzing dirty samples.
Inlet liners for splitless injection are generally designed as straight tubes, although new designs such as the gooseneck will help contain the sample in the injector. Packing these liners with wool will also help trap non-volatile residue and prevent column contamination.
For the capillary injector on the Clarus 590 or 690 GC system.
