Abstract
An isocratic technique was developed for the analysis of luteinizing hormone releasing hormone (LHRH) by high performance liquid chromatography (HPLC) using 210 nm UV detection, ZORBAX ODS column (4.6 mm × 15 cm), mobile phase (86% triethylamine phosphate buffer: 14% acetonitrile), and 1.5 mL/min flow rate. The coefficient of variation (C.V.) for precision and proportionality assays was lower than 5% for all concentrations studied. The detection limit of LHRH was 1 ng/mL.
