A simple, rapid, and robust ultrahigh-performance liquid chromatography (UHPLC) method has been developed for the simultaneous determination of natural and artificial vanilla flavouring substances as well as some precursors has been developed using an automated method scouting or method optimization workflow. The most suitable mobile phase and stationary phase combination was identified in a scouting run. These conditions were used to create a two-dimensional model in computer simulation software. Temperature and gradient time were varied to establish the optimum fast and robust separation conditions. This approach resulted in a 5.5 min gradient method that allowed for fast screening of 11 compounds of interest.
