Questions regarding the conversion and calculation of gas chromatography data

Thread Content

The gas sample was analyzed using a FID gas chromatograph, which was calibrated with methane. The analysis results showed 15,000 ppm of total hydrocarbons; if the material consisted entirely of benzene, what would be the concentration of the gas sample in g/m3?

If benzene is used as the reference, then you should use benzene as a standard to calibrate the measurement system. It is also possible to calculate by correlating the carbon content of total hydrocarbons with that of benzene.
