Abstract

The elution order of dinitrobenzene isomers was a function of the methanohwater ratio in the eluent when using a C₁₈ packing but not a phenyl packing. The order for the isomeric dihydroxybenzene was always the same. Retention times were longer for the phenyl packing, but that may have reflected the (unknown) extents of derlvatizatlon.
