HPLC Method for Octanoic acid (Caprylic acid) on Primesep 100 by SIELC Technologies

High Performance Liquid Chromatography (HPLC) Method for Analysis of Octanoic acid (Caprylic acid).
Octanoic acid (Caprylic acid) is the common name for the eight-carbon straight-chain fatty acid. It can be found in numerous foods such as coconuts, cherries, plums, pineapple sages, black raspberries, and shallots. Octanoic acid is found to be associated with medium-chain acyl-CoA dehydrogenase deficiency, a genetic disorder that affects the metabolism of converting certain fatty acids to energy.
Octanoic acid can be retained on a mixed-mode Primesep 100 column by using an isocratic method consisting of a 50/50% Acetonitrile (ACN) and water mobile phase with a Phosphoric acid (H3PO4) buffer. UV detection at 210 nm.
