Although various in-silico methods and software have been developed to mitigate the experimental burden needed for LC method development , these computational approaches are typically used for optimizing analytical separations given results across an array of experimental conditions that are rarely applied to purification workflows . Quantitative structural retention relationship (QSRR) modeling is an alternative approach that utilizes physiochemical descriptions of analytes and fits mathematical models to associate these descriptors to retention time . Once trained, QSRR models can be utilized and predict the retention times for analytes with structures not used when developing these models. These models can then be employed for downstream tasks, as demonstrated by our various reported QSRR modeling approaches for small molecules .
