In the process of equipment operation, the customer on the basis of affirming the function of the equipment, put forward a lot of improvement suggestions, the company according to the customer's suggestions to optimize the design of the equipment to meet the requirements of the customer's factory mass production.

Second, the system composition

1. PLC control system and software

(1) It can control multiple pumps for gradient elution (that is, the pump can operate at any flow rate in any proportion, for example, pump A from 0% to 100% and pump B from 100% to 0%, but the total value is 100%; or pump A from 17% to 88% and pump B from 83% to 12%, the sum of the flow rates is any value within the set flow rate), and each pump can also be controlled separately.

(2) Automatic sampling, elution and collection are carried out according to the pre-designed working mode, and can be operated in infinite cycles.

(3) Control the injection pump to inject accurately.

(4) Control the valve to switch and collect the working mode.

(5) Control the detector for signal collection and feedback, and realize automatic switching and collection according to time and peak height.
