Hi,
i would like to separate the impurities of vinyl chloride monomer.( The ethyl chloride and mono-vinylacetylene leave in the descent of the peak of the majority one.)
I use a DBWAX Etr in 60mx0.32mm.
For the methyl chloride, I make the analysis on a HP-Plot Q.
I also have: ethylene / butane / transbutene / butene / 1.2 dichloroethane
What is the best column to make this separation ?
Could you please tell me if I must make this analysis on two columns with a switching valve?
thanks
T.
