Thanks, Karlos!
I was thinking about NBS too, but I don't know where to get it. I ask my friend Fery, he do lot's of organics and he is from the same country, so
maybe he know where to get NBS here. I read about utilizing NBS in determination of sorbic acid. I have some issues with sorbic acid too, I will try
to change conditions today, maybe it will help. |
