To compare with database of Kovat's retention index，we can find out that X is most probably to be isobutene.In addition， another GC should be performed under the same conditions with pure isobutene for further confirmation.
4.13.2 Evaluation 
（1） Scale of Operation 
Analytes present at levels from major to ultratrace components have been successfully determined by gas chromatography.Depending on the choice of detector，samples with major and minor analytes may need to be diluted before analysis.The thermal conductivity and flame ionization detectors can handle larger amounts of analyte；other detectors， such as the electron capture detector or a mass spectrometer， require substantially smaller amounts of analyte.Although the volume of sample injected is quite small （often less than a microliter）， the amount of available material from which the injection volume is taken must be sufficient to be a representative sample.For trace analytes， the actual amount of analyte injected is often in the picogram range. 
（2） Accuracy 
The accuracy of a gas chromatographicmethod varies substantially from sample to sample.For routine samples，accuracies of 1%～5% are common.For analytes present at very low concentration levels， for samples with complex matrices， or for samples requiring significant processing before analysis， accuracy may be substantially poorer.
