SO₂ Isesengura

Ibisobanuro ku bicuruzwa

Isesengura rya dioxyde de sulfure (SO₂) ni igikoresho cyo gusesengura gaze gishingiye kuri ultraviolet absorption spectroscopy na algorithm ya Differential Optical Absorption Spectroscopy (DOAS). Urumuri rumuri rutangwa nisoko yumucyo rwibanze kandi ruhujwe na fibre optique. Yanduzwa binyuze muri fibre optique kuri selile yo hanze yubushyuhe bwo hejuru. Nyuma yo kunyura muri selile ya gaze no kwinjizwa na gaze yagenewe, urumuri rwoherezwa nindi fibre optique kuri spekrometero. Imbere ya spekrometero, urumuri rutatanwa no gusya, kandi ibimenyetso bya optique bitatanye bihindurwamo ikimenyetso cyamashanyarazi na detector ya array, bityo bikabona amakuru yikurikiranya ya gaze. Ukurikije aya makuru yerekana, igikoresho gikoresha algorithm ya DOAS kubara ubunini bwa gaze yapimwe.
