✦ Synopsis

A study was made of two highly polar polyester stationary phases for the separation of fatty acids in the Cls CZo range. These stationary phases were also compared to moderately polar stationary phases currently in use. The most complete separation was obtained using DEGS-PS. The fastest separation was obtained with SP-216PS, a new polyester, in the absence of Czo.
