## Description\n
It is a app for predicting retention times in HPLC and recommend the best HPLC column type for chromatographic enantioseparation.\n\n
Input:\n
·smile_1 and smile 2: smiles of two molecules (especially enantiomers)\n
·input_eluent: the ratio of eluent (hexane/2-propanol). For example: input 0.02 for hexane/2-propanol=98/02\n
·input_spped: the flow rate of HPLC (mL/min)\n
·column_name: select a column type in the dropdown\n
Output:\n
·The predicted retention time for two molecules
·The separation probability (Sp) of two molecules, a higher Sp indicates that the molecules is easy to separate in HPLC under given condition (see Citation 1).\n

## Function\n
Single prediction: predict a compound under a given condition including eluent, flow rate and column type\n
Column recommendation: give the separation probability of two molecules (especially enantiomers) under all column types\n
