(A) Mass spectrum of co-eluting TMS derivatives of C₂₈ prim/sec diol isomers and major fragmentations of main isomer. (B) EICs showing intensities of m/z 73 and of short α-fragments of main isomer and the four next most abundant isomers. a.u.: arbitrary units. (C) Mass spectrum of co-eluting Ac derivatives of C₂₈ prim/sec diol isomers and major fragmentations of main isomer.
