As you know, Gas Chromatography equipped with flame ionization detector (GC/FID) has the ability to perform quantitative measurements, and Gas Chromatography equipped with a Mass spectrometer (GC/MS) has the ability to perform qualitative analysis. In this work we provided a DATABASE for the Gas Chromatograph with flame ionization detector to enable it to perform qualitative analysis along with quantitation. A mixture of complex volatile compounds was used to evaluate and compare different linear velocities of the carrier gas (N2) and different temperature programs of column (DB-5) to determine the parameters used to optimize the separation. After, a series of saturated aliphatic n-Alkanes (C14 – C17) was injected into the gas chromatograph in the optimized operating conditions to determine their specific retention times and to apply in Kovat’s equation and evaluate the quality of unknown compounds situated in that field of retention times.
