A new static-analytic apparatus equipped two ROLSI TM capillary samplers was presented.The proposed improvements allow ROLSI TM to perform in-situ sampling even at P < P carrier gas. The apparatus has shown comparable performances to existing methods, while showing some advantages. Two binary systems of interest were investigated. New systems are expected to be investigated for various applications in chemical engineering. The liquid sampling mechanism is expected to be used for liquid-liquid equilibrium measurement.
