- The liner is a crucial component of the GC sampling system. The sample vaporizes within the liner, mixes thoroughly with the carrier gas, and then enters the GC column uniformly. Therefore, the liner also has a significant impact on the stability of the analysis results.
- Based on the geometric differences of the liner, it can be categorized into Single Taper, Focus, Straight and Taper focus.
- Based on the difference in sample injection methods, they can be classified into split liners, splitless liners, and split/splitness liners.
- For complex matrix samples, selecting a liner filled with glass wool can effectively reduce contamination of the GC column.
- For the analysis of active pesticides or alkaline compounds, using an inert liner tube yields better results.
