Dear collegues,
I am interested in the separation of a- and b- carotene by means of
HPLC.
On this topic I have two questions:
1. Does anybody have a nice method that seperates these two carotenes.
At the moment I use a RP C 18 column and isocratic conditions of
CH3CN:Dichloromethane:Methanol. As result I get a double peak and this
makes cochromatography not easy.
2. Does anybody have a nice source for isolated a-carotene that I can
use as a standard for the qualitative and quantitative analysis?

Regards, Holger
