Optimal inlet performance      Agilent offers a complete line of liners for your Agilent GC splitless inlet. Agilents proprietary deactivation is important for splitless liners because of the longer sample/liner contact in splitless mode.
When deciding between a liner with or without glass wool, choose a liner without glass wool if your sample contains non-volatiles or analytes within a wide boiling range. For unknown samples, use a liner without glass wool to avoid loss of active or labile compounds.
