Liner selection and injection techniques in GC

In GC, you can choose from a wide variety of liners, which can make selection feel overwhelming. Fortunately, a few basic criteria can guide you to the best liner for your application. Liner selection depends first on the injection technique used and whether the sample is a liquid or a gas. Additionally, certain sample matrices and/or components can be challenging to evaporate and transfer, requiring special attention when selecting the optimal liner.

Key Learning Objectives:

• Understand how injection technique (e.g., split, splitless, on-column) and sample type (liquid vs. gas) influence liner selection.
• Identify the basic selection criteria that narrow down the best liner for a given application.
• Recognize challenging sample matrices and components that require special liner considerations.
