I am new in GC-FID and TCD measurement technique. I will analyze a gas stream at high temperature above 190 oC in the GC-FID system. I want to construct a calibration curve for the mixture of components. But two of my components are in gaseous phase (each 1% in N2 gas) and others are in liquid phase (like ethanol, acetaldehyde, 1-butanol etc.). Moreover, I have checked that none of the components has exactly the same retention time (well separated).
I have gas-bag also and the system is connected with heating reactor, where I will use N2 gas as a carrier gas.
The system is mixture of components and N2 as a carrier gas. I have GC-FID and GC-TCD to detect various components and gases.
How do I calibrate my GC-FID for the system?
In advance, Thanks
Please look at the following below links which may help you in your analysis:

It is not clear what are plan to do. In small concentrations these liquid componunds will be fully evaporated (like in TEFLAR bag).
You need to prepare gas mixtures with known concentrations of each compound at few calobration levels. You liquids you can inject weighted few uL into the TEDLAR bag to known volume of N2.
