| Objectives of Sample Introduction - Representative aliquot from bulk sample
- Fast vaporization in inlet liner
- Expanded sample gas volume contained within inlet liner
- Homogeneous mixing in liner
- Representative transfer to column
| | Inlet Liners - Important Considerations - Must ensure complete vaporization of the sample before it reaches the column entrance
- Must not react with the sample
- The liner volume must be larger than the volume of vaporized sample
- Should minimize discrimination not promote it
- Adding quartz wool will increase the surface area of the sample and promote mixing
- Liner should be deactivated especially for analysis of polar solutes and for splitless injections
- Quartz wool should be placed in the optimum position
