3081ALiquid automatic samplerSample pretreatment equipment for chromatograph

Main characteristics

1) Easy to operate, 5.0-inch visual human-machine interactive touch interface.

2) Intelligent operation, user input mode, achieving intelligent prompts for gradual input.

3) High stability, real-time feedback comparison of encoder, and more stable instrument operation.

4) Provide multiple modes of I/O ports, compatible with gas chromatography from different manufacturers.

5) High degree of automation, unmanned operation, 24-hour uninterrupted work.

6) Beautiful appearance, small size, light weight, easy installation, and strong universality.

7) The injection rod adopts a buffer mechanism, which reduces the dead volume of injection.

8) The sample disk adopts an absolute position encoder to compensate for the accumulated errors during operation.

9) The instrument adopts a modular design and adopts a dual line CAN communication mechanism internally, with strong expandability of functional modules.

10) Adopting precision motor drive, providing multiple driving speeds, stable injection speed, and precise injection quantification.

11) Provide a universal Modbus communication protocol and USB universal interface to facilitate the development of user control programs on the upper computer.

12) Safe error verification: After the user inputs data, the system verifies the data to ensure safer operation of the instrument.

13) The PC based upper computer software has full reverse control to improve user efficiency.

14) 160 digit sample disk expansion, supporting dual tower injection, with a time reproducibility of less than 1/1000 second for synchronous injection.
