Mapping of retention time between system A and B

Welcome to PredRet

PredRet is a user-driven database of compound retention times. The purpose is to be able to predict the retention time (RT) of a compound in one (your!) chromatographic system if it has been experimentally determined in another chromatographic system by someone, somewhere in the world.


The aim is to help the identification process since compounds that are not compatible with the observed RT can be disregarded. Confirmatory experiments can then be reserved for compounds that could have the observed RT.


We hope that this will allow researchers to complete the feature annotation and compound identification process in a faster and more rational manner and thus save time and resources, both monetary and environmental.
