Abstract

Identifikasi kandungan zat makro pada obat-obatan kimia sangat diperlukan untuk tujuan perlindungan kesehatan masyarakat. Dalam penelitian ini, identifikasi magnesium (Mg) dalam produk farmasi dilakukan menggunakan LIPS (Laser-Induced Plasma Spectroscopy). Laser yang digunakan pada penelitian adalah laser Nd: YAG dan laser CO₂. sampel yang digunakan adalah tablet suplemen. Sinar laser diarahkan dan difokuskan oleh lensa cembung pada sampel. Berkas plasma diinduksikan pada permukaan sampel. Spectrum emisi yang tajam dan berintensitas tinggi yang terdeteksi menggunakan laser Nd:YAG menunjukkan adanya kandungan Kalsium (Ca) dan Magnesium (Mg) pada sampel. Hasil yang diperoleh kemudian dibandingan dengan pengujian sampel menggunakan laser CO₂. Diperoleh hasil intensitas spectrum Mg jauh lebih tinggi menggunakan laser CO₂.

Keywords
