Abstract

Telah dirancang peralatan apektroskopi sederhana yang dapat digunokan untuk melihat spektrum dan mengidentiEkasikan Imam. yang dipancarkan oleh sampel dari Cu, 7n, KC1, Nal dan NaCI. Prinsip peralatan ini adalah terjadinya loncatan bunga api listrik tegangan tinggi di antara dua elektrods. Loncatan bunga api itu berfungsi untuk mengeksitasikan cuplikan. Pada saat kembali ke tingkat energi yang lebih rendah akan memancarkan foton yang kemudian diuraikan oleh kisi difraksi sebagai spektrum cahaya tampak . Hasil dari penelitian aetelah dicocokkan dengan lampiran B didapatIcan unsur Cu dengan panjang gelombang (5114,001 ± 0,977)A, unaur CI dengan panjang gelombang (4828,910 ± 0,757)A, unsur dengan panjang gelombang (478,434 ± 0,718)A , unsur Na dengan panjang gelOmbang (5643,343 ± 1,562)A dan unaur Na down panjang gelombang (5811,742 ± 0,982)A. It have been designed a simple spectroscopy instrument with can be used to see the spectrum and to identify element which emitted by sample of Cu, Zn, KCI, Nal and NaCI. The instrument principle was the accuration of the high voltage discharge between to electrodes. The discharge can used to excite the sample when the sample return to the lower energy level then the level before would emitted foton which would spread by difraction grafting as visible light spectrum. The research result which had been matched with the in suplement 13 were Cu element with (5114.001 ± 0.977)A wavelength, were CI element with (4828.910 ± 0.757)A wavelength, were Zn element with (4768.434 ± 0.718)A wavelength, were Na element with (5643.343 ± 1.562)A wavelength, were Na element with (5811.742 ± 0.982)A wavelength.
