go for GCMS

Raul Vera

Google the Laboratory Procedures in Animal Science Research written by M. L. Galyean. Chapter on GC includes protocol for VFAs

Fadi Hassanat

Here is a protocol used for one of my studies it is long because the rune time takes 35 minutes. With GC the run takes 7 minutes.

Good luck

Volatile FA were analyzed using an HPLC (Series 1200; Agilent Technologies Canada Inc.). The HPLC was equipped with a refractive index detector and

Aminex HPX-87H column (300 × 7.8 mm) packed with sulfonated divinyl benzene-styrene copolymer [Bio-Rad Laboratories (Canada) Ltd., Mississauga, ON, Canada]. The mobile phase was 0.005 M sulfuric acid and the flow rate was 0.6 mL/min.
