hexane = clean-up solvent?
« on: December 29, 2009, 06:06:21 AM »
Hi everybody,

I'm wondering for the benomyl extraction where hexane is added to the acidiified sample extract in a sep. funnel, what is its purpose? In meat, it would be to remove lipids...but testing benomyl in Fruits and Veggies, what would adding hexane do? Also, after all the ethyl acetate washes, the ethyl acetate gets evaporated and acetonitrile is used to reconstitute the compound.
what does acetonitrile do to carbendazim, the break-down compound of benomyl?

any help is appreciated!!
 ;D

hexane can be used to remove lipid interferences in a blended samples mixture. however, if my samples are Fruits and veggies like lettue, strawberries etc., is hexane still serving the same purpose in this case?

thx  ;)

Hexane will remove anything non-polar.  Google QuEChERS.
