HPLC-MS Method for Analysis of Lamivudine on Primesep 100 Column
Lamivudine is an antiviral medication used primarily to treat infections caused by the human immunodeficiency virus (HIV) and hepatitis B virus (HBV). It belongs to a class of drugs known as nucleoside reverse transcriptase inhibitors (NRTIs).
Lamivudine can be retained, and analyzed using a Primesep 100 mix mode stationary phase column. The analysis utilizes a isocratic method with a simple mobile phase consisting of water, acetonitrile (MeCN), and Ammonium Formate pH 3.0 – 20 mM as a buffer. Detection is carried out using UV, LC-MS.
