Abstract
흡수분광분석장치와 반사분광분석장치가 결합된 형태의 복합분광분석장치를 제작하여 흡수분광분석과 반사분광분석의 성능을 서로 비교하였다. Cu2+이온표준용액과 Co2+이온표준용액들을 사용한 실험결과에 의하면, 분석대상성분의 농도가 너무 묽은 경우나 분석대상성분의 몰흡광계수가 충분히 크지 않은 경우와 같이 기존의 흡수분광분석으로는 정량분석이 힘든 시료용액에 대한 분광분석에 용이하게 적용될 수 있다는 사실을 확인하였다.

A combined spectrometer which could function as either the absorption spectrometer or the reflectance spectrometer was built and used for the comparison of the applicabilities of the two types of spectrometers. According to the results the sensitivity of the reflectance spectrometry was found to be useful for the quantitative analysis when the concentration of the analyte was too low or the molar absorptivity of the analyte was too small for one to perform the quantitative analysis using the absorption spectrometry.
