High Performance Liquid Chromatography (HPLC) Method for Analysis of Diazepam .
Diazepam , also known as Valium , is a benzodiazepine. It is thought that benzodiazepines work by enhancing the activity of certain neurotransmitters in the brain. Diazepam increases the activity of gamma-aminobutyric acid (GABA), a special chemical that can send signals throughout the nervous system.
Diazepam can be retained in HPLC on Newcrom R1 reverse-phase column with the simple isocratic mobile phase consisting of acetonitrile (MeCN) and water. The analysis method can be UV detected at 240 nm.
