HPLC Analysis of Fatty Acids with MS Compatible Conditions

June 4, 2011

View Application

Fatty acids are carboxylic acids with a long unbranched carbon chain. They are hydrophobic compounds with different number of carbons. Most naturally occurring fatty acids have a chain of an even number of carbon atoms. Three fatty acids are separated on a Primesep 100 HPLC column by reversed-phase mechanisms. This general HPLC method and mixed-mode column can be used for separation of other fatty acids.

Application Column

Primesep 100

The Primesep family of mixed-mode columns offers a wide variety of stationary phases, boasting unprecedented selectivity in the separation of a broad array of chemical compounds across multiple applications. Corresponding Primesep guard columns, available with all stationary phases, do not require holders. SIELC provides a method development service available to all customers. Inquire about our specially-tailored custom LC-phases for specific separations.
