Head space analysis(HSA)법에 의한 이성분계 기액평형 측정방법을 개발하였다. 이 방법은 보정고선을 필요치 않기 때문에 일반 HSA법보다 신속하고 정확하게 실험을 수행할 수 있으며, 이 방법에 따라 측정한 몇 2성분계의 기액평형조성을 동일조건하의 문헌치와 비교한 결과, 좋은 일치성을 보임을 확인하였다. 따라서 본 HSA용 기액평형 측정방법을 간단하고 정확한 등온 기액평형 측정방법으로 제시한다.
The new calculation method, for the determination of binary vapor-liquid equilibrium(VLE) by HSA, is suggested in this work. It makes experiment more rapid and precise than ordinary HSA method, since it did not need calibration curve. Several binary VLE data were determined with this method and these data showed good agreement with the literature data at the same condition. Therefore the new calculation method discussed in this work could be used as a simple and accurate method for a measurement of isothermal VLE data.
