If the reaction yield does not reach the expected level, the next synthesis reaction is stopped, which has the effect of eliminating wasted reaction reagents and time.
- the switching of the flow path by each valve is performed based on the detection result of the detector 9, but the scheduled sugar modification processing is performed, and the reaction is performed in advance. If the passage time of the eluate in the column or the separation column is known, the switching of each valve may be controlled by the passage of time without depending on the result of the detector 9.

- the six pumps 1, 2, 24 to 27 send the solutions of bottles 13 to 17 at a constant flow rate and for a fixed time, respectively, under the control of the controller 11.
- the difference from Example 1 is that the sugar nucleotide solution (X “S 2 -S 2 , X 3 -S 3 ) was directly supplied to the reaction column 18 to 20 (R ⁇ R 2 , R 3 ).
- the pumps 1 and 2 only send the same buffer 14, and a so-called low-pressure gradient function is not required.
- pumps 25, 26, and 27 send sugar nucleotide solutions (X—SX 2 —S 2 , X 3 —S 3 ) to reaction columns 18 to 20 without passing through the respective solenoid valves. Therefore, opening and closing of the solenoid valves is different from the low pressure gradient function which is synchronized with the suction process of the pump, more precisely, primer one (P) and sugar nucleotide solution (Xi- x 2 - s 2, x 3 - There is an effect that it is possible to control the time during which s 3 ) is fed.

- the pumps 1 and 2 only feed the buffer 14 or the buffer 30 and do not need a so-called low-pressure gradient function.
- the primer (P) and the sugar nucleotide solution (X 1 -S 1, x 2 -S 2 , x 3 -s 3 ) are introduced into the channel via the sample injector in required amounts. Therefore, unlike the low pressure gradient function in which the opening and closing of the solenoid valve is synchronized with the pump suction process, the primer (P) and the sugar nucleotide solution (x — s x 2 — s 2 , x 3 — s 3 ) This has the effect that wasteful consumption can be eliminated.
- FIG. 8 is a system configuration diagram of the present embodiment
- FIG. 9 is a flow diagram.
- either one detector or two detectors may be used. If the analysis time has already been set, the control may be performed without using the detector.
- the difference from Example 3 is that the separation columns and valves connected in series to the respective reaction columns are combined into one separation column. Another difference is that an ultrafiltration column 40 was used as the separation column.
- a non-revolution 41 is provided in place of the valves 6 to 8 by sharing the separation force ram.
- the configuration of the ultrafiltration ram 40 is shown in FIG.
- the ultrafiltration ram 40 has a cylindrical ultrafiltration membrane 48 inside, and also discharges components having a large molecular weight that do not pass through the membrane among the components introduced from the inlet 45. There are two outlets, one outlet 47 for discharging the components passing through the membrane, and the other outlet 46 for discharging the components passing through the membrane.
- the ultrafiltration membrane 48 is selected so that, for example, the primer does not pass and the sugar nucleotide—nucleotide passes.
- the molecular weight of the primer is about 10 000 or more, and the molecular weight of the sugar nucleotide ⁇ nucleotide is about 400. Because of this, there are considerable differences in size and they are easily separable.
- a three-way valve 42 Downstream of the discharge port 47, a three-way valve 42 is provided. This valve is configured to selectively communicate the flow path on the detector side with one of the outlets 46 and 47. The flow path of the discharge port on the side that is not communicated is blocked by the valve.
- this ultrafiltration column 40 Separation on this ultrafiltration column 40 is performed as follows. That is, when the eluate from the reaction column is introduced, the three-way valve 42 is set to the outlet 46 side, and only the permeate through the ultrafiltration membrane 48 is discharged. The high molecular weight primer and the sugar bound to the primer remain on the ultrafiltration membrane 48 ⁇ . After a lapse of a predetermined time, when the three-way valve 42 is switched to the outlet 47 side, the primer and the sugar bound to the primer accumulated in the ultrafiltration membrane 48 are discharged to the detector side.
- the operation in this embodiment is basically common to the operation shown in the first embodiment. You. Although the separation column is shared, the valve 41 is switched to the flow path on the dotted line at the timing when the valves 6 to 8 in Example 1 are switched to the drain. The same operation as in Example 1 can be realized.
- the configuration of the apparatus can be simplified by using a common separation column. Also, by using an ultrafiltration column as the separation column, the primer (P) is once concentrated in the ultrafiltration column. Accordingly, the problem of the broadening of the primary (P) band as described in Step 3 of Example 1 is eliminated, and there is an effect that introduction into the next reaction column is facilitated.
- the present invention is applied to a sugar chain synthesizing apparatus, synthesis or separation of a sugar chain can be easily performed.
