설명

분석 메모

Prior to analysis of samples, AOAC Method 2012.13 requires that system resolution be verified to ensure sufficient separation of the C18:1 cis/trans isomers. This is done by injecting a cis/trans FAME column performance mix (40495-U), a qualitative mix that contains a mixture of C18:1 trans and C18:1 cis isomers. Resolution is calculated between two groups of FAME isomers. Group 1 = C18:1Δ13t and C18:1Δ14t, whereas group 2 = C18:1Δ9c (oleic acid) and C18:1Δ10c. A resolution value of >1.0 is considered acceptable. As shown, the resolution value calculated using the SP-2560 column is R=1.12.
