General description

Inlet liner is an important part within the injection port. The prime functions of the inlet liner are to limit sample degradation and improve vaporisation along with correctly positioning the syringe needle. A wrong choice of liner can have prominent effect on the chromatogram. The basic problems related with incorrect choice of liner include the higher potential of peak tailing and mass discrimination. The inlet liner volume is recommended to be larger than the amount of sample injected by syringe so as to avoid any reaction with the sample. Injector port liner is suitable to make connection between sample introduction and GC column. Direct type has narrow bore which sustains a high linear velocity through the injection port to diminish band broadening and transferring all the samples to column.
Deactivated (silanized) glass inlet liner for capillary injection ports.
