Simultaneous determination of tumour biomarkers homovanillic acid, vanillylmandelic acid, and 5-hydroxyindole-3-acetic acid in human urine using single run HPLC with a simple wall-jet glassy carbon electrochemical detector

HPLC with amperometric detection (HPLC-ED) was used for the simultaneous determination of tumour biomarkers homovanillic acid (HVA), vanillylmandelic acid (VMA), and 5-hydroxyindole-3-acetic acid (5-HIAA) in one run in human urine using inexpensive lab-made glassy carbon wall-jet detector. Simple an...
