I think it’s too condensed to be really deemed correct. The term is indeed synonymous with chromatography on silica hydride-based phases though – where there is typically the manifestation of both reversed-phase and normal phase interactions within a single gradient run, hence the ability to acceptably (retention, peak shape, selectivity etc) chromatograph compounds of widely varying polarity within said single run. I much prefer the definition given in the Bioanalysis Glossary:- A variant of normal phase liquid chromatography, i.e. the stationary phase is more polar than the mobile phase, but for which the mobile phase components and additives are water-miscible. HILIC and much chromatography on silica hydride-based phases are popular examples of ANP.
