ABSTRACT:
The identification of magnesium (Mg) in pharmaceutical products was carried out using LIPS (Laser-Induced Plasma Spectroscopy). The lasers used in the research were Nd: YAG laser and CO2 laser. The sample used was a supplement tablet. The laser beam is directed and focused by a convex lens on the sample. The plasma beam is induced on the sample surface. The sharp and high-intensity emission spectrum detected using the Nd: YAG laser indicates the presence of Calcium (Ca) and Magnesium (Mg) in the sample. The results obtained were then compared with sample testing using a CO2 laser. The results of the Mg spectrum intensity were much higher using a CO2 laser.
KEYWORDS:LIPS, Nd: YAG, Magnesium, Calsium
