Hello,

I want to calibrate C4 hydrocarbons on a GC and would like to ask if one has experience with this. Is the detectorsignal identical for the isomers (1-butene + 2-butenes + i-butene and n-butane + i-butane)? I would like to know if we have to order all isomers or for example 1-butene and n-butane are enough if the retention times are known. I have FID.

Thanks

The response factor will be all the same. Variation is +/- 5% or less. The biggest difference will be between butane and butene.

Hey Stepan,

thanks a lot. I want to calibrate one olefin and one alkane but then I need one of each.
