General Description

Inlet liner is an important part within the injection port. The prime functions of inlet liner are to limit sample degradation and improve vaporisation along with correctly positioning of 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. Split type has wide bore with 2 or 4 mm I.D. which is suitable for solvent extraction. Cups are used to enable sample mixing.
OV-1 is a modified silicone polymer which has good temperature stability. It is suitable as liquid phases in chromatography. The least polar is a dimethylsilicone which is sold under the mane OV-1.
