Under the supervision of the Dean of the College of Pharmacy, Professor Dr. Sarmed H. Kathem Alkhateeb, the Continuing Education Unit at the University of Baghdad/College of Pharmacy, held an in-person workshop entitled “An Overview of Liquid Chromatography/Mass Spectrometry Technique (LC/MS),” delivered by Assistant Professor Dr. Nour Sabah Jaafar, a faculty member at the Pharmacognosy and Medicinal Plants Department. The workshop aimed to define the liquid chromatography/mass spectrometry technique. The workshop included several topics, including a general description of the technique, its working mechanism, the components of the instrument, the stationary and mobile phases used in this technique, and the characteristics and type of samples used with each phase. In the LC/MS technique, the constituents of a liquid sample are partitioned between two immiscible phases (stationary phase and mobile phase). Following separation, the analytes undergo ionization. The mass analyzer then resolves these ions according to their mass-to-charge ratio. The workshop concluded that LC/MS is a highly precise analytical tool that plays a crucial role in determining the molecular structure of unknown compounds through fragmentation analysis. It also provides highly accurate chemical structure information, making it essential in pharmaceutical and analytical applications.
