Abstract	분광분석장치의 구성성분들인 광원과 광 검출기를 cell을 중심으로 은쪽에배열하여 제작한 반사분광분석장치를 제작하였으며, 이러한 분사분광분석장치가 액체시료에 대한 흡수분광분석에 사용될 수 있는지를 알아보았다. 이를 위해 Cu2+이온의 표준용액들을 대상으로 반사분광분석장치와 기존의 흡수분광분석장치를 대표하는'Spectronic 20' 성능을 비교한 결과, 1.0 ×10-⁴M~1.00 ×10-⁴M 농도 범위에서 반사분석장치는 'Spectronic 20'에 비해 더 높은 감도를 나타내었다. We have constructed and tested a new reflectance spectrometer. Both the radiation source and the detector are embedded on the same side of the cell compartment..Its performance has been compared with that of the conventional absorption spectrometer ('Spectronic 20') using standard solutions of Cu2+. The sen-sitivity of the reflectance spectrometer was found to be much higher than that of'Spectrortic 20' over the ana-lytical concentration range of l.O0 ×10-⁴M and 1.00 ×10-¹M of Cu2+.
