WIPO Patent Application WO/2017/033256
Kind Code:
A1
Abstract:
Provided is a separation/purification apparatus capable of adjusting the mixing ratios of a mobile phase and an eluting solvent contained in a collected solution. The separation/purification apparatus is provided with: a liquid supply means for supplying the eluting solvent to the entrance of a trap column; a channel switching means for selectively connecting the exit of the trap column to a waste liquid channel or a collection channel; a liquid supply amount measuring means for measuring the amount of the eluting solvent supplied to the trap column by the liquid supply means; and a channel control means for controlling the channel switching means to connect to the collection channel at the time when the amount of the eluting solvent supplied to the trap column has reached a predetermined initial waste liquid amount, and thereafter controlling the channel switching means to connect to the waste liquid channel at the time when a predetermined solution collection amount has been reached. The separation/purification apparatus is thus able to adjust the mixing ratio of the collected solution.
