Abstract

Provided is a supercritical fluid apparatus including: an analysis flow path through which a mobile phase flows; a back-pressure control valve provided at a downstream end of the analysis flow path to adjust pressure in the analysis flow path to a predetermined pressure; a small-diameter pipe connected to the outlet of the back-pressure control valve, having an inner diameter allowing internal pressure to be maintained at a pressure higher than the atmospheric pressure; a large-diameter pipe connected to a downstream end of the small-diameter pipe, having a larger inner diameter than the small-diameter pipe; and a large-diameter pipe heating part for heating the large-diameter pipe.
