The standard used
was the Supelco mix of 37 compounds (Sigma Aldrich) and individual
patterns for the identification of C18:1 trans-11 (vaccenic
acid), C18:2 cis-9 trans-11, C18:2 trans-10 cis-12 (Nu-CheckPrep)
and C18:1-OH (Sigma Aldrich) were obtained. The dataset acquisition
was performed using the software Chem Station (Agilent
Technologies).
