Hi Dhamodharan,

look up for the five-point pH titration method

It was shown to be very accurate and it is relatively simple and cheap

Hi Dr. Henrik Andersen, Thanks for sharing

Hello Everyone, I would Like to know that whether Is there any simple procedure for estimating the Volatile Fatty acids in the given sample. I need a procedure which is very simple and which can be done by simple glass wares and instruments like Ph meter and burettes. I am not able to remember the procedure. Can any one who knows about this could share the ideas about this. Thank you very much. 

The methods in the two references I mentioned fulfill these criteria.

Additionally there is a titration procedure which my department has evaluated.

Thank you Dr. Henrik Andersen ... I will try this method to detemine the VFA in rumen liquid. Is it possible to try for that sample too?

Thank you Dr. Henrik I was having trouble of the same nature.
