摘要：
The liquid microcolumn chromatograph comprises a microcolumn (1), unit (2) for feeding eluent, made as a reservoir (3) separated by a "slack" diaphragm (4) into two half-chambers (5,6) one whereof communicates with a source (7) of pressure and the other is connected to a source (8) of eluent and to an inlet into the microcolumn (1) a flow-through cell (9), and an eluent-collecting vessel (14). The chromatograph is provided with an additional reservoir (10) separated by a "slack" diaphragm (11) into two half-chambers (12, 13) and is also provided with an additional source (15) of pressure, the half-chamber (12) being communicated with an outlet of the flow-through cell (9) and connected to the eluent-collecting vessel (14), whereas the half-chamber (13) communicates with the additional source (15) of pressure.
