Inlet Liners for GC High Concentration Analyses

Answer

This Information Applies To: Agilent GC Systems with Split/Splitless (S/SL) inlet

Issue

Different liners are required for different high concentration, split analysis techniques including:

• General use liners 
• Auto inject, general use
• Auto inject, viscous sample
• Auto inject, dirty matrix
• Manual slow injection
• Headspace (HS) and purge and trap (P&T). 

Inlet liner choice is part of method validation, and the same liner type must be used consistently while running that method. For help with identifying the correct inlet liner for your application, see GC Liner Selector Tool.
