I have a question regarding the determination of Ethylene Oxide with GC-FID using head-space. Since I have prepared a vary concentrated solution of Ethylene Oxide I cant observe any peak.
The parameters for the head space are: equilibration time: 45 min, equilibration temperature : 70C, transfer line temeperature: 75C, pressuration time: 1min , injection time : 1min.
Can someone suggest me another programme for the head space?
Please help me

Thank you in advance
