The retention time of drugs used in therapeutic drug monitoring using PNIPAAm hydrogel modified-bead columns. Retention times of mycophenolic acid and methotrexate were obtained using pH 4.80 CH3COONH4 buffer solution as mobile phase. All other drugs used pH 6.75 CH3COONH4 buffer solution mobile phase.
