Spektrometri merupakan suatu metode analisis kuantitatif yang pengukurannya berdasarkan banyaknya radiasi yang dihasilkan atau yang diserap oleh spesi atom atau molekul analit. Salah satu bagian dari spektrometri ialah Spektrometri Serapan Atom (SSA), merupakan metode analisis unsur secara kuantitatif yang pengukurannya berdasarkan penyerapan cahaya dengan panjang gelombang tertentu oleh atom logam dalam keadaan bebas (Skoog et. al., 2000).

Prinsip Spektroskopi Serapan Atom
Metode ini berprinsip pada absorbsi cahaya oleh atom. Atom-atom menyerap cahaya tersebut pada panjang gelombang tertentu, tergantung pada sifat unsurnya. Dengan absorpsi energi, berarti memperoleh lebih banyak energi, suatu atom pada keadaan dasar dinaikan tingkat energinya ketingkat eksitasi. Keberhasilan analisis ini tergantung pada proses eksitasi dan memperoleh garis resonansi yang tepat. Lebih lanjut mengenai materi ini klik link di bawah ini:
