Second dimension retention indices in “normal” orthogonality comprehensive two-dimensional gas chromatography using single standard injection generated isovolatility curves

This work builds upon recent developments in the field of second dimensional (2D) retention indices (RI) for use in comprehensive two-dimensional gas chromatography (GC×GC), expanding application to the most commonly used “normal” orthogonality column configuration, where 2D RI are rarely employed.
