1,102,279. Chromatography system. CESKOSLOVENSKA AKADEMIE VED. 11 May, 1965 [26 May, 1964], No. 19818/65. Heading B1X. An arrangement for conveying solutions to chromatographic columns comprises at least one sample reservoir (ZT Fig. 2), at least one column (V), a plurality of eluent reservoirs (R 1 , R 2 , R 3 ) and a corresponding number of metering pumps (P 1 , P 2 , P 3 ), each of the reservoirs being connected to a respective pump and the pumps being connected to the column(s) through a common conduit (P) into which a capillary outlet from said sample reservoir(s) is also connected, and at least one pump being controlled 'by a mechanical programmer. In a modification (see Fig. 1) one pump (Pv) receives the outflows from the remainder, a valve (D) is provided having an outlet connected to said pump, the sample reservoir(s) (Z b ) and the reservoir corresponding to said pump (Rv) are connected to the valve and the line(s) connecting the sample reservoir(s) to the valve is of capillary tubing. Fig. 3 (not shown) illustrates an arrangement for distributing solutions to a plurality of columns. The apparatus is particularly suitable for the separation of amino acid solutions using eluents blended in desired proportions by the pumps. |
