Dear Dr Deepti Yadav,

I think this article (in attached) may actually help you in your research.

Best wishes,

ms′′ is the moles of standard and me′′ is the unknown moles of epoxide. Thus, from the equation (4) me′′ has been calculated as all other terms are known. Therefore, % GC yield= [moles of epoxide (me′′) / {moles of olefin (mo′) + moles of epoxide (me′′)}]×100.

Supplementary material for the determination of %GC yield:

You can remove the sample time to time take GCMC chromatogram. find our the area under peak of starting material & product . Take ratio of the product to the reactant x100= percentage conversion.

How can calculate the conversion of the product using GC-MS?

PHB (%) = PHB weight (g/L) × 100/total cell dry weight (g/L)
