Until recently, METLIN SMRT had virtually no competition as a dataset for training predictive models for HPLC. In early 2024 a new repository of HPLC retention times emerged -RepoRT . The RepoRT repository contains 373 datasets measured in different laboratories and on different instruments, including 295 RP and 71 HILIC datasets. Some other less common stationary phases (such as pentafluorophenyl) were also considered.
